Oligosaccharides with free hemiacetal group

These compounds are generally named glycosyl[glycosyl]n glycoses with the connectivity locants placed in round brackets between the individual component terms. The same format is used for the specific short formulae customary in carbohydrate chemistry. For disaccarides of that type Chem. Abstr. still uses the traditional 0-locants in front of the full name.

Carb-37.2. Oligosaccharides with a free hemiacetal group... 

In the nomenclature of oligosaccharides, trivial names are still used for a number of substances (e.g. maltose, cellobiose or trehalose. Figure 4.5). In the case of reducing disaccharides, systematic nomenclature takes as its basis the name of the monosaccharide with a free hemiacetal hydroxyl group, which is preceded by the name of the substituted monosaccharide and the respective anomeric configuration is indicated (a- or P-). Disaccharide maltose (Figure 4.5), formed by condensation of...
