Ascorbic Acid [50-81-1] (1) is the name recognized by the lUPAC-IUB Commission on Biochemical Nomenclature for Vitamin C (1). Other names are L-ascorbic acid, L-xyloascorbic acid, and L-// fi (9-hex-2-enoic acid y-lactone. The name...

The lUPAC-IUB Commission on Biochemical Nomenclature (13) recommends that the term vitamin B 2 be used as the genetic descriptor for aU. cottiaoids exhibiting quaUtatively the biological activity of cyanocobalamin. However, because of its commercial importance, cyaaocobalamin is used iaterchangeably with vitamin B 2 heteia. 

In 1981, the lUPAC-IUB Joint Commission on Biochemical Nomenclature proposed that there be a set of trivial names for the important vitamin D compounds, including calciol [67-97-0] for vitaminD, calcidiol [19356-17-3] ion 25-hydroxy-vitaminD, and calcitriol [32222-06-3] ion 1 a,25-dihydroxy-vitamin D. This nomenclature has met with varying degrees of acceptance, as has the proposal to use calcine [69662-75-5] (deoxy-vitamin D2) and ercalcine [68323-40-0] (deoxy-vitamin D ) to name the triene hydrocarbon stmcture for 9,10-j (9-cholesta-5,7,10(19)-ttiene and...

Note The formal lUPAC-IUB Commission on Biochemical Nomenclature convention for the definition of the torsion angles polypeptide chain (Biochemistry 9 3471-3479, 1970) is different from that used here, where the atom serves as the point of reference for both rotations, but the result is the same.

These Recommendations expand and replace the Tentative Rules for Carbohydrate Nomenclature [1] issued in 1969 jointly by the IUPAC Commission on the Nomenclature of Organic Chemistry and the IUB-IUPAC Commission on Biochemical Nomenclature (CBN) and reprinted in [2]. They also replace other published JCBN Recommendations [3-7] that deal with specialized areas of carbohydrate terminology however, these documents can be consulted for further examples. Of relevance to the field, though not incorporated into the present document, are the following recommendations ... 

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.
