IUPAC-IUB Commission on Biochemical Nomenclature

Not all problems were solved, however, and different usages were encountered on the two sides of the Atlantic. A joint British-American committee was therefore set up, and in 1952 it published Rules for Carbohydrate Nomenclature [18]. This work was continued, and a revised version was endorsed in 1963 by the American Chemical Society and by the Chemical Society in Britain and published [19]. The publication of this report led the IUPAC Commission on Nomenclature of Organic Chemistry to consider the preparation of a set of IUPAC Rules for Carbohydrate Nomenclature. This was done jointly with the IUPAC-IUB Commission on Biochemical Nomenclature, and resulted in the Tentative Rules for Carbohydrate Nomenclature, Part I, 1969 , published in 1971/72 in several journals [1]. It is a revision of this 1971 document that is presented here. In the present document, recommendations are designated 2-Carb-n, to distinguish them from the Carb-n recommendations in the previous publication.

Fig. 6.1. IUPAC-IUB Commission on Biochemical Nomenclature rules defining residues and peptide units in peptides. In the example shown, residue No. 2 contains the backbone atoms N2, C2, and C2. Peptide unit No. 2 contains the backbone atoms C2, C2, and Nf. Rj, R2, and R3 are the side chains of the amino acid residues (www.chem.qmul.ac.uk/iupac/AminoAcid/).

It is extremely difficult to maintain uniform nomenclature or abbreviations for these molecules due to the diverse nature of the saccharide moiety and the continual discovery of new glycosphingolipids. A semi-systematic nomenclature for glycosphingolipids has been recommended by the IUPAC-IUB Commission on Biochemical Nomenclature,7 and has been reviewed in some detail.8-10 Readers are urged to consult these articles in order to become familiar with the no-... 

This abbreviation is approved by the IUPAC-IUB Commission on Biochemical Nomenclature and is typical of the kind of alphabet soup that is making biochemistry almost completely unintelligible without a glossary of approved (and unapproved) abbreviations at hand at all times. We shall make minimum use of such designations. You will remember we already use Z for something else (Section 19-7).

It is worthwhile to begin the discussion by first stating the conventions adopted for the description of polypeptide conformation. These conventions (Edsall et ah, 1966) were discussed at the 1965 Gordon Conference on Proteins some additional nomenclature was suggested at a workshop on protein conformation in Madras in January 1967. The whole subject is, at present, under consideration by the IUPAC-IUB Commission on Biochemical Nomenclature.
