streptobiosamine [Supplementary Concept]
represents about two-thirds of the streptomycin molecule; structure
Date introduced: January 1, 1978
Polysaccharides
Long chain polymeric CARBOHYDRATES composed of MONOSACCHARIDES linked by glycosidic bonds.
Oligosaccharides
Carbohydrates consisting of between two (DISACCHARIDES) and ten MONOSACCHARIDES connected by either an alpha- or beta-glycosidic link. They are found throughout nature in both the free and bound form.
Disaccharides
Oligosaccharides containing two monosaccharide units linked by a glycosidic bond.
Carbohydrates
A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES.
Year introduced: /metabolism was CARBOHYDRATE METABOLISM 1963-1965
Sugars
Short chain carbohydrate molecules that have hydroxyl groups attached to each carbon atom unit with the exception of one carbon that has a doubly-bond aldehyde or ketone oxygen. Cyclical sugar molecules are formed when the aldehyde or ketone groups respectively form a hemiacetal or hemiketal bond with one of the hydroxyl carbons. The three dimensional structure of the sugar molecule occurs in a vast array of biological and synthetic classes of specialized compounds including AMINO SUGARS; CARBASUGARS; DEOXY SUGARS; SUGAR ACIDS; SUGAR ALCOHOLS; and SUGAR PHOSPHATES.
