| glucuronide | <biochemistry> A substance produced by attaching glucuronic acid to another substance with glycosidic bonds. Toxic substances can be removed from the body in this manner - glucuronic acid is introduced into the body, the acid forms a glycosidic bond with the toxic substance and neutralises it, and the resulting glucuronide is eventually excreted.

| glucuronose | An obsolete term for glucuronic acid. (05 Mar 2000) |
| glucuronosyltransferase | <enzyme> A family of enzymes accepting a wide range of substrates, including phenols, alcohols, amines, and fatty acids. They function as drug-metabolizing enzymes that catalyze the conjugation of udpglucuronic acid to a variety of endogenous and exogenous compounds. Chemical name: UDPglucuronate beta-D-glucuronosyltransferase (acceptor-unspecific) Registry number: EC 2.4.1.17 (12 Dec 1998) |
| glucuronoxylan | <biochemistry> H Emicellulosic plant cell wall polysaccharide containing glucuronic acid and xylose as its main constituents. Has a _(1-4) xylan backbone, with 4-0 methylglucuronic acid side chains. Arabinose and acetyl side chains may also be present. Major polysaccharide of angiosperm wood (hardwood). (18 Nov 1997) |
| glucuronoxylan xylanohydrolase | <enzyme> From higher plants; hydrolyzes beta (1-4)-xylosyl linkages to yield oligomeric species; glucuronosyl moieties as side chains are required Registry number: EC 3.2.1.- Synonym: glucuronoxylanase (26 Jun 1999) |

| glue proteins, drosophila | Glycosylated proteins which are part of the salivary glue that drosophila larvae secrete as a means of fixing themselves to an external substrate for the duration of the pre-pupal and pupal period. The proteins which consist of at least eight polypeptides are encoded in the third larval instar by the sgs-3, sgs-4, sgs-7 and sgs-8 genes. (12 Dec 1998) |
| glue-sniffing | Inhalation of fumes from plastic cements; the solvents, which include toluene, xylene, and benzene, induce central nervous system stimulation followed by depression. See: solvent inhalation. (05 Mar 2000) |
