Amino sugars nomenclature

If the glycosidic oxygen link is replaced by -0-NH-, normal amino sugar nomenclature can be employed. 

The nomenclature of the glucosamine and chondrosamine derivatives referred to in this article is essentially that used in the literature. A few minor changes have been made in order to effect a greater uniformity and precision in the classification. No attempt has been made to introduce any new nomenclature of the 2-amino sugar derivatives. It is now accepted that they are more correctly designated as the 2-amino-2-deoxy-sugars.

If the lactolhydroxyl group is substituted by NHj at C-atom i, one speaks of glycosylamines, or, by substitution with NHR, of iV-glycosides. Glyc-amines are i-amino-i-deoxy sugar alcohols. The nomenclature of the compounds found in nature, which are formed partly or entirely from amino sugars, is still not uniform. ... 

The use of d- and L-prefixes is a nomenclature for orientation of atomic structure of sugar and amino acid molecules. It is a structural definition and is not related to the optical properties. 

Sugar amino acids (Saa) 1 are carbohydrate scaffolds that carry an amino and a carboxy function.12 Due to their structural and functional diversity, no detailed nomenclature for this class of amino acids has yet been established. Saa are found in nature as subunits of oligosaccharides (neuraminic acid 1) in cell walls of bacteria (muraminic acid 2) and in some antibiotics 3-6 (Scheme l). 2-8 ... 

D-Glyceraldehyde is the same as (iJ)-glyceraldehyde. However, the D or L label is not related to the R,S nomenclature (i.e. a D-enantiomer could be either an iJ-enantiomer or an 5-enantiomer). This nomenclature is still used to assign natural products including sugars and amino acids (see Sections 11.1 and 11.3). 

This old-fashioned nomenclature is generally only used to show amino acids and sugars, which can contain several asymmetric centres (see Sections 11.1 and 11.3). 

Because of die somewhat ambiguous definitions of D and L, another system of nomenclature was devised for asymmetric compounds, and it has largely replaced foe old D, L-system since foe 1960s. However, foe D, L-nomendature is stfo used for amino adds and sugars.
