glyco-|glaɪkəʊ, glɪkəʊ| irregularly used (instead of glycy-) as a combining form of Gr. γλυκ-ύς sweet, and in names of chemical compounds to indicate the presence of glycerol or some other substance with a name beginning with glyc-. In mod. chemical nomenclature, usu. used to refer to sugars generally, in contradistinction to gluco-: so glycose, glycoside, etc. (cf. glucose, glucoside). ˌglyco-benˈzoic, -cyˈamidine, -ˈcyamine (see quots.); glyco-ˈgelatin, a combination of glycerine and gelatin used in the making of lozenges and pastilles; glycoˈhæmia (see quot.); glycoˈlipid Biochem., any substance which is a combination of both a carbohydrate (or carbohydrate derivative), esp. a sugar, and a lipid; ˈglycophyte Ecology, a plant whose growth is inhibited by saline soil (cf. halophyte s.v. halo-); hence glycoˈphytic a.; glycoˈprotein (also † -proteid) Biochem., any of a group of proteins with one or more usually relatively short side chains composed generally of a mixture of carbohydrates or carbohydrate derivatives; glycoˈtropic a. Biochem., antagonistic to insulin.

1940Jrnl. Biol. Chem. CXXXII. 178 The cerebroside..belongs to a new class of *glycolipids which probably differ from previously described cerebrosides only because they contain glucose in place of galactose. 1970C. N. Graymore Biochem. Eye vii. 507 Cerebrosides and gangliosides may also be classified as glycolipids, both containing hexoses.
1947R. F. Daubenmire Plants & Environment ii. 61 Because salts so evidently interfere with the absorption of water by *glykophytes, saline soils have long been considered ‘physiologically dry’..for these plants. 1964V. J.
