| glycolate | A salt or ester of glycolic acid. (05 Mar 2000) |

| glycoleucine | <chemical> Chemical name: Norleucine (12 Dec 1998) |
| glycolic | <chemistry> Pertaining to, or derived from, glycol; as, glycolic ether; glycolic acid. <chemistry> Glycolic acid, an organic acid, found naturally in unripe grapes and in the leaves of the wild grape (Ampelopsis quinquefolia), and produced artificially in many ways, as by the oxidation of glycol, whence its name. It is a sirupy, or white crystalline, substance, HO.CH2.CO2H, has the properties both of an alcohol and an acid, and is a type of the hydroxy acids. Synonym: hydroxyacetic acid.

| glycolic acid | <biochemistry> Hydroxyacetic acid, found in young plants and green fruits. Glycolate is formed from ribulose 1,5 bisphosphate in a seemingly wasteful side reaction of photosynthesis, known as photorespiration. (18 Nov 1997) |
| glycolic acid dehydrogenase | <enzyme> Enzyme from human liver converts glycolate to oxalate, acceptor not identified, not oxygen; free glyoxylate is not an intermediate Registry number: EC 1.1.- (26 Jun 1999) |
| glycolic aciduria | Excessive excretion of glycolic acid in the urine; a primary metabolic defect due to deficiency of 2-hydroxy-3-oxoadipate carboxylase, resulting in excretion of glycolic and oxalic acids, leading to the clinical syndrome of oxalosis. (05 Mar 2000) |
| glycolide | <chemistry> A white amorphous powder, C4H4O, obtained by heating and dehydrating glycolic acid. Alternative forms: glycollide. Origin: Glycol + anhydride. Source: Websters Dictionary (01 Mar 1998) |
| glycolipid | <biochemistry> Oligosaccharides covalently attached to lipid as in the glycosphingolipids found in plasma membranes of all animal and some plant cells. The lipid part of glycolipids is sphingosine in which the amino group is acylated by a fatty chain, forming a ceramide. most of the oligosaccharide chains belong to one of four series, the ganglio, globo, lacto type 1 and lacto type 2 series. Blood group antigens are glycolipids. (18 Nov 1997) |
| glycolipid lipidosis | <disease> Lysosomal storage disease caused by a deficiency of alpha-galactosidase a and resulting in an accumulation of globotriaosylceramide in the renal and cardiovascular systems. The disease is characterised by telangiectatic skin lesions, renal failure, and disturbances of the cardiovascular, gastrointestinal, and central nervous systems. Inheritance: x-linked.

| glycols | A generic grouping for dihydric alcohols with the hydroxy groups (-oh) located on different carbon atoms. They are viscous liquids with high boiling points for their molecular weights. (12 Dec 1998) |
| glycoluric | <chemistry> Pertaining to, derived from, glycol and urea; as, glycoluric acid, which is Synonym: hydantoic acid. Origin: Glycol + uric. Source: Websters Dictionary (01 Mar 1998) |
| glycoluril | <chemistry> A white, crystalline, nitrogenous substance, obtained by the reduction of allantoin. Origin: Glycolyl + uric. Source: Websters Dictionary (01 Mar 1998) |
| glycolyl | <chemistry> A divalent, compound radical, CO.CH2, regarded as the essential radical of glycolic acid, and a large series of related compounds. Origin: Glycolic + -yl. Source: Websters Dictionary (01 Mar 1998) |
| glycolylurea | <chemistry> A derivative of urea, C3H4N2O2, obtained from allantion, as a white, crystalline substance, with a sweetish taste. Synonym: glycolyl urea. Origin: Hydrogen + allantion. Source: Websters Dictionary (01 Mar 1998) |
| glycolysis | <biochemistry> The conversion of a monosaccharide (generally glucose) to pyruvate via the glycolytic pathway (i.e. The Embden Meyerhof Parnas pathway) in the cytosol. Generates ATP without consuming oxygen and is thus anaerobic. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
