Oligosaccharides with Free Hemiacetal Group
These compounds are generally named glycosyl[glycosylln 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 Chern.
Abstr. still uses the traditional O-locants in front of the full name.
