glycoside

noun    (Concise Encyclopedia)

Any of a wide variety of naturally occurring organic compounds in which a carbohydrate portion consisting of one or more sugars or sugar derivatives is combined with a hydroxy compound (a compound containing an OH group). Since sugars themselves are hydroxy compounds, polysaccharides are glycosides by definition. Other glycosides include various flower and fruit pigments, several antibiotics (e.g., streptomycin), and the cardiac glycosides (see digitalis).
