Research Excerpts

Overview

Scleroglucan is a high-molecular water-soluble microbial exopolysaccharide and mainly applied in the fields of petroleum, food, medicine and cosmetics. It is produced by the basidiomycete Sclerotium rolfsii and appreciated as a multipurpose compound.

Drug Classes (1)

ClassDescription
oligosaccharideA compound in which monosaccharide units are joined by glycosidic linkages. The term is commonly used to refer to a defined structure as opposed to a polymer of unspecified length or a homologous mixture. When the linkages are of other types the compounds are regarded as oligosaccharide analogues.
