Part 1. Their Shorthand Notation and Systematic Names

Introduction

In the late 1990s, Rich O. Adlof and Professor Frank D. Gunstone prepared an alphabetical list of English trivial names of fatty acids. They also included the structure of these fatty acids in this list and indicated their sources. Now the need has been felt to overhaul this list, explain the shorthand notation system, which is commonly used but has never been formally described, and also include systematic names in accordance with the IUPAC Nomenclature of Organic Chemistry, and especially to make it multilingual.

This has been done in two ways. For Japanese and Russian, the translations of the English names have been included in a table (Part 2, Table 3). Professor Masanori Arita of the National Institute of Genetics, Mishima, Japan, took care of the Japanese names by transcribing the English names into Japanese scripts (Katakana, Hiragana and Kanji). Dr Maria L. Domoroshchenkova of the All-Russia Scientific Research Institute of Fats, St Petersburg, saw to the Russian names by looking up what Russian names existed. Their valuable contributions are hereby warmly acknowledged.

For several Western European languages, I compiled sets of transcription rules that allow English names to be converted into local names. N.B. The English verb ‘to compile’ is derived from the Latin verb compilare meaning to plunder or plagiarize, so that is what I have done. Accordingly, these transcription rules allow chemists to arrive at ‘novel’ trivial names in their own language and thus enjoy the ease of communication that English-speaking chemists enjoy without them realising their privilege.

Because the transcription rules are published as a website, other languages can be included at a later stage. So if a Swede or Turk wants to help his/her fellow countrymen by providing them with names in their language, he/she can do what I did for the languages included so far. See what trivial names already exist, look for a pattern, design some provisional translation rules, check these with the existing names and decide which existing names are to be treated as exceptions.

So I studied lists of trivial names in the various languages concerned. Dr Carmen Dobarganes, recently retired from the Oils & Fats Institute of the University of Seville provided me with a list of Spanish names, Dr Suzana Ferreira-Dias of the School of Agriculture of the University of Lisbon provided a list of Portuguese names and Professor Lanfranco Conte of the Department of Food Science of the University of Udine, saw to the Italian names. In addition, they commented on my proposed translation rules. For the German translation rules I made extensive use of the “Seed oil fatty acids” database sent to me in pdf-format by Dr. Bertrand Matthäus of the Max Rubner Institut, Detmold. I greatly appreciate the help and the interest they have taken in my work; it has been a valuable and essential support. I am also most grateful for the comments and suggestions for improvement my draft versions have received. Without them, there would have been more omissions and typing errors.

 

Shorthand notation of fatty acids

Articles dealing with lipids commonly use a shorthand notation. Like trivial names, they save space and contribute to rapid understanding. For instance, “18:0” (formerly C18:0”) stands for stearic acid, first briefly legitimized nearly 50 years ago but never expanded beyond a common range of fatty acids (www.jlr.org/content/8/5/523.full.pdf+html). So it is high time to do something about it and this list of trivial names of fatty acids provides an excellent opportunity to provide a set of rules to arrive at a shorthand notation. In fact, I made an earlier attempt (Corps Gras, Doc. K 330v2, Éditions Techniques de l’Ingénieur, Paris, 2013) based on how Adlof and Gunstone arrived at their shorthand notations.

The present rules incorporate several improvements nearly all of which have been suggested by Dr Bill Christie. Spaces that were prescribed in the earlier version of the shorthand notation rules have been replaced by commas. This has the advantage that if the name is too long for a line and has to be split into two, it will now be split at hyphens rather than at the space. Accordingly, the hyphens can be maintained when the two parts are rejoined.

If the rules listed below are insufficiently clear or raise questions, looking at examples in Table 1 below may provide the answer.

1. Each shorthand notation of monobasic fatty acids ends with two numbers that are separated by a colon.
  The first number indicates how many carbon atoms the straight fatty acid chain contains. The second number indicates how many non-single bonds are present in this chain.
  1.1. So palmitic acid, a saturated fatty acid with a chain of sixteen carbon atoms is written as: 16:0
  1.2. Linolenic acid, an unsaturated fatty acids with three double bonds and a chain length of eighteen carbon atoms becomes: 18:3
2. The number of non-single bonds is the sum of double and triple (acetylenic) bonds.
  2.1.

Accordingly, ‘crepenynic acid’, (9Z)-octadecen-12-ynoic acid, a fatty acid with a carbon chain of eighteen atoms, which contains a double bond at the 9-position and a triple bond at the 12-position will end in: 18:2
3. Punctuation marks inside the shorthand notation are used as follows:
  3.1. There are no spaces inside the shorthand notation.
  3.2.

The only place where a colon is used is between the number indicating the number of carbon atoms in the straight fatty acid chain and the number of non-single double bonds.
    3.2.1.  ‘Lauric acid’ is written as 12:0.
  3.3. A comma is used to separate numbers and to separate groups of substituents or substituents from the non-single bond descriptors.
    3.3.1.  An example showing a comma separating two numbers is provided by ‘ipurolic acid’, 3,11 Dihydroxytetradecanoic acid, which has the following shorthand notation: 3,11-diOH-14:0.
    3.3.2.  An example showing group separation is provided by a fatty acid containing for instance both hydroxyl groups and methyl groups such as acetonic acid, 2-hydroxy-2-methylpropanoic acid, which becomes: 2-OH,2-Me-3:0
    3.3.3.  An example of a fatty acid that contains a group of substituents and non-single double bonds by coriolic acid, (9Z,11E)-13-Hydroxy-octadeca-9,11-dienoic acid, the shorthand notation of which is 13-OH,9c11t-18:2, also shows the use of a comma to separate position numbers.
  3.4.

A hyphen is used between what precedes the number indicating the fatty acid chain length and this number and between the number or numbers indicating the position of substituent groups and the symbol indicating the kind of groups.
    3.4.1.  So oleic acid becomes 9c-18:1
    3.4.2.  The acetonic acid 2-OH,2-Me-3:0 mentioned earlier also illustrates the use of the hyphen
  3.5.

Alcharnoic acid ((Z)-14,15 epoxy-11-icosenoic acid) has an epoxy group with a cis configuration. This can be indicated in the shorthand notation by a ‘c’ before the position numbers concerned and a hyphen in between c-14,15-ep,11c-20:1
  3.6. A hyphen is also used for diacids to separate this descriptor from the number of non-single bonds.
    3.6.1.  Adipic acid is therefore 6:0-diacid
4.

Just as in systematic names, the positions of the double bonds are indicated by the numbers of the carbon atoms at which they start, whereby the carbon atom of the carboxyl group has number 1.
  If the fatty acid contains more than one non-single bond, the list starts with the lowest carbon number.
  4.1. An example of a fatty acid with more than one double bond is for instance linolenic acid: 9c12c15c-18:3.
5.

The configurations of the double bonds are indicated by the position of the double bond followed by the letter c if it has a cis-configuration or the letter t if it has a trans-configuration.
  The use of c and t is preferred to the use of the suffixes Z and E as used in the systematic names because these letters are pronounced rather differently in different languages. The Z is pronounced ‘zed’ in UK-English but as ‘zee’ in US-English, whereas in German, it is pronounced as ‘tset’. There is no need to write the c or t in italics for this purpose; this saves typing effort.
  5.1. So oleic acid becomes: 9c-18:1 and its trans-isomer, elaidic acid, becomes: 9t-18:1.
6.

Terminal double bonds and the double bond linking an alkylidene group (this is an alkyl group linked from a secondary carbon atom by a double bond) to the terminal atom of the fatty acid carbon chain, which double bonds are neither cis or trans are indicated by e
  6.1. Undecylenic acid (10-undecenoic acid), which has a terminal double bond, has the following shorthand notation: 10e-11:1.
7. Triple bonds are indicated by a.
  7.1. Tariric acid (6-octadecynoic acid) becomes: 6a-18:1.
8.

There are no punctuation marks between the groups consisting of position number and configuration, but when the configuration is not indicated, a comma separates the position numbers; a hyphen is inserted between the last of these groups and the number indicating the fatty acid chain length.
  8.1.

The trivial name dehydromatricaric acid (2-Decen-4,6,8 triynoic acid) applies to both the cis and the trans isomers. Its shorthand notation is therefore: 2,4a6a8a-10:4.
9. The presence of a hydroxyl group is indicated by the position of this group followed by a hyphen and OH.
  Like the non-single bond descriptors, the information concerning the hydroxyl group is separated from the number indicating the fatty acid chain length by a hyphen. If deemed to be necessary, stereodescriptor (R or S) can be written after this number.
  9.1. Accordingly, jalapinolic acid, (11S)-hydroxyhexadecanoic acid, is written as 11-OH-16:0 or 11S-OH-16:0.
10. The presence of two or more hydroxyl groups is indicated by diOH, triOH etc., preceded by the numbers of their positions separated by commas.
  10.1. So aleuritic acid, 9,10,16-trihydroxyhexadecanoic acid becomes: 9,10,16-triOH-16:0.
11.

If the fatty acid also contains double or acetylenic bonds, these are mentioned after the hydroxyl groups and before the number indicating the fatty acid chain length; they are separated by a comma.
  11.1.

Therefore, ricinoleic acid, (9Z,12R)-12-hydroxy-9-octadecenoic acid, has the following shorthand notations: 12-OH,9c-18:1 or 12R-OH,9c-18:1
12. Methyl groups that are attached to the fatty acid carbon chain are indicated by Me, diMe, triMe, etc.
  These are preceded by the number or numbers of their position, where necessary separated by a comma and connected by a hyphen. Like the hydroxyl groups they are written before the description of the non-single double bonds, which number can be zero.
  12.1.

Accordingly, geranic acid, (2E)-3,7-dimethylocta-2,6-dienoic acid, has the following shorthand notation: 3,7-diMe,2t6e-8:2. I have chosen this example because it also illustrates the use of the double bond descriptor e.
13.

When both hydroxyl and methyl substituents are present, their alphabetical order is maintained so that the hydroxyl groups are listed first (H < M). Then, separated by a comma, the methyl groups are listed and followed by a hyphen and the number of carbon atoms in the fatty acid chain.
  13.1. So acetonic acid, 2-hydroxy-2-methylpropanoic acid becomes: 2-OH,2-Me-3:0.
14.

The only diacids listed in the Tables are α,ω diacids. Their shorthand notation includes the suffix diacid that is separated by a hyphen from the number indicating the number of non-single double bonds.
  14.1. Accordingly, succinic acid (butanedioic acid) becomes: 4:0-diacid.
  14.2 And an unsaturated diacid such as citraconic acid ((Z)-2-Methyl-2-butene-dioic acid) becomes 2-Me,2c-4:1-diacid.

In addition to double bonds, acetylenic bonds, hydroxyl groups, methyl groups, and terminal carboxyl groups, fatty acids may contain other functional groups. They are far less common so it is an open question whether or not they have to be included in the shorthand rules. Since they were in the original system used by Adlof and Gunstone, they are shortly discussed below:

15. The symbol Cp stands for a cyclopentenyl group.
  For alphabetical reasons, it precedes the hydroxyl groups if present. As with the previous substituents, their position precedes the substituent and there is a hyphen between the two. If a further substituent is listed, a comma is inserted. The position of the double bond in the cyclopentene ring is not specified.
  15.1. Accordingly, hydnocarpic acid, 11-(2-Cyclopent-1-yl)-undecanoic acid becomes: 11-Cp-11:0.
  15.2.

And gorlic acid, (Z)-13-(2-Cyclopent-1-yl)-6-tridecenoic acid, chosen as an example to illustrate the use of this comma has the following shorthand notation: 13-Cp,6c-13:1.
16.

The symbol P stands for a cyclopropane or cyclopropene group. The symbol is preceded by the numbers of the carbon atoms that form part of this group as in malvalic acid: 8,9-P,8c-17:1. The systematic name of this acid is: 8,9-methylene-8-heptadecenoic acid.
17.

The symbol oxo indicates the presence of a keto-group at the indicated position. The position precedes the word “oxo” and a hyphen separates them.
  17.1. So lactarinic acid is written as 6-oxo-18:0. In the shorthand notation, oxo comes after methyl.
18. The oxa symbol indicates an ether linkage at the position indicated.
  But whereas in the systematic name of ‘colnoleic acid’ (9-(nona-1,3-dienyloxy)-8-nonenoic acid), the two carbon chains are numbered individually, in the shorthand notation, this acid is treated as an 18:3 with an ether link with the numbers continuing along the oxygen-interrupted chain.
  18.1. Accordingly, colnoleic acid becomes: 9-oxa,8t10t12c-18:3.
19. The symbol ep stands for an epoxide bridging the two carbon atoms indicated by their numbers.
  19.1.

So coronaric acid, (Z)-9,10-epoxy-12-octadecenoic acid, becomes c-9,10-ep,12c-18:1, where the c indicates the stereochemistry of the carbon atoms forming the epoxide. Again just ‘c’ rather than cis.

 

Systematic names of fatty acids

Systematic names of chemical compounds can be arrived at by applying the rules issued by the International Union of Pure and Applied Chemistry (IUPAC) but in practice, this is less straightforward than it sounds. When working on the list and trying to arrive at their systematic names, I have consulted the “Seed oil fatty acids” database sent to me in pdf-format by Dr. Bertrand Matthäus, Max Rubner Institut, Detmold, and the Chemspider website, the free chemical database operated by the Royal Society of Chemistry. By comparing the names for the same compounds in these databases, I saw that their approaches to systematic chemical names differed. In fact, the German database provided three alternatives for linoleic acid: Z,Z-9,12-Octadecadienoic acid, Octadeca-9c,12c-dienoic acid and 9c,12c-Octadecadienoic acid, whereas Chemspider gave: (9Z,12Z)-9,12-Octadecadienoic acid. Another website also puts the carbon numbers and the conformational descriptor in front of the name: 9Z,12Z-octadeca­dienoic acid. It turns out that none of these names is correct.

I therefore consulted the Dutch version of the IUPAC Nomenclature. Section E (Stereochemistry) has an example: (2E,4Z)-Hexa-2,4-dieenzuur that shows that the conformational descriptors: E (trans) and Z (cis), are in italics and placed at the front of the name with the carbon atom numbers to which the double bond refers before them and that the numbers are repeated before the indication how many double bonds there are; in this example before the ‘‑dienoic’. So the correct way turns out to be: (9Z,12Z)-octadeca-9,12-dienoic acid.

On an earlier page of this book, the example: (Z)-2-Methyl-2-buteenzuur (angelic acid) shows that if there is only one double bond, the carbon atom number is omitted before the conformational descriptor and placed before the name indicating the chain length. So according to IUPAC rules, oleic acid becomes: (Z)-9-Octadecenoic acid. The example also illustrates that the conformational descriptor is positioned right in front of the systematic name. And this is how I arrived at names in the original version of the table on this website.

However, the books on nomenclature I had used turned out to superseded. As pointed out to me by Dr Ursula Bünzli-Trepp, the IUPAC rules had changed in 2013: now the carbon atom number in the monounsaturated fatty acid is no longer omitted before its conformational descriptor and it is no longer placed before the name indicating the chain length. This change brought the monounsaturated fatty acids in line with the polyunsaturated ones. So ‘oleic acid’ was no longer ‘(Z)-9-octadecenoic acid’ but had become ‘(9Z)-octadec-9-enoic acid’, cf. the systematic name of ‘linoleic acid’: ‘(9Z,12Z)-octadeca-9,12-dienoic acid’.

I therefore decided to update the list and I am most grateful to Dr Bünzli, who kindly edited my efforts and while doing so, spotted several mistakes. She changed my ‘8,9-methyleneheptadecanoic acid’ (dihydromalvalic acid) to ‘7-(2-octylcyclopropyl)­heptanoic acid’, she pointed out that stereodescriptors should be listed in order of increasing locants. So my ‘(10E,15Z,9R,12R,13R)-trihydroxyoctadeca-10,15-dienoic acid’ (fulgidic acid) became (9R,10E,12R,13R,15Z)-9,12,13‑trihydroxyoctadeca-10,15‑dienoic acid’.

The systematic names listed in Table 1 are the so-called Preferred IUPAC Names (PIN). However, there is another nomenclature system that is used by Chemical Abstracts (CA) and is therefore more common in the US. In the CA-system, the locant in monounsaturated fatty acids remains before the name but it is preceded by the conformational descriptor. So for oleic acid we have:

  • Old IUPAC:                           (Z)-9-octadecenoic acid
  • New IUPAC (PIN)                (9Z)-octadec-9-enoic acid
  • Chemical Abstracts (CA)    (9Z)‑9-octa­decenoic acid

There are some further differences between the IUPAC system and the CA system, such as for instance:

  • To indicate a chain length of twenty atoms, the IUPAC system uses ‘icosa’ whereas the CA system uses ‘eicosa.
  • The CA system uses conjunctive names for a (saturated) hydrocarbon-chain component with a principal group attached to a ring component (less enclosing marks). So ‘alepramic acid’ becomes ‘2-cyclopentene-1-propanoic acid’ in the CA system whereas its PIN is ‘3‑(cyclopent-2-en-1-yl)propanoic acid’.
  • The way the stereogenic axes of allenes are expressed also differs between the two systems. The IUPAC system indicates this by a subscripted ‘a’ Ra and Sawhere the CA system writes R and S.

Both systems have retained several trivial names like ‘butyric acid’, ‘palmitic acid’, ‘adipic acid’ etc. In Table 1 below, the systematic names of the acids that kept their trivial names have been put between parentheses: ‘(oleic acid)’.
