| glucagon | A polypeptide hormone (3485 D) secreted by the cells of the Islets of Langerhans in response to a fall in blood sugar levels. Induces hyperglycaemia. A family of structurally related peptides includes glucagon like peptides 1 & 2 (encoded by the same gene), gastric inhibitory polypeptide, secretin, vasoactive intestinal peptide, growth hormone releasing factor, pituitary adenylate cyclase activating polypeptide, exendins. (18 Nov 1997) |

| glucal | An unsaturated sugar derivative in which the adjacent hydroxyl groups are removed, one of which is that upon the carbon-1 of the aldose (or carbon-2 of the ketose), yielding a CH==CH between these two positions. Synonym: glucal. (05 Mar 2000) |
| glucan | One of a group of polysaccharide sugars composed of D-glucose monomers linked together by glycosidic bonds. Examples of glucans are dextran, laminarin, and lichenin. (09 Oct 1997) |

| glucan 1,4-alpha-glucosidase | <enzyme> An enzyme that catalyses the hydrolysis of terminal 1,4-linked alpha-d-glucose residues successively from non-reducing ends of polysaccharide chains with the release of beta-glucose. It is also able to hydrolyze 1,6-alpha-glucosidic bonds when the next bond in sequence is 1,4. Chemical name: 1,4-alpha-D-Glucan glucohydrolase Registry number: EC 3.2.1.3 (12 Dec 1998) |
| glucan 1,4-alpha-maltohexaosidase | <enzyme> From klebsiella pneumoniae; hydrolyzes 1,4-alpha-d-glucosidic linkages in amylaceous polysaccharides so as to remove successive maltohexaose residues from the non-reducing ends Registry number: EC 3.2.1.98 Synonym: exo-maltohexao-hydrolase, extracellular maltohexaose-forming amylase, bacillus maltohexaose-forming amylase, g6-amylase (26 Jun 1999) |
| glucan 1,4-maltotetraohydrolase | <enzyme> Releases successive maltotetraose residues from the non-reducing chain ends of amylaceous polysaccharides Chemical name: 1,4-alpha-d-glucan maltotetraohydrolase Registry number: EC 3.2.1.60 Synonym: maltotetraose-forming amylase, maltotetraohydrolase, exo-maltotetraohydrolase (26 Jun 1999) |
| glucan 1,6-alpha-isomaltosidase | <enzyme> Hydrolyzes 1,6-alpha-d-glucosidic linkages in polysaccharides so as to remove successive isomaltose units from the non-reducing ends of the chains; from arthrobacter globiformis; mw 66 kD; genbank d30761 Registry number: EC 3.2.1.94 Synonym: isomalto-dextranase, 1,6-alpha-d-glucan isomaltohydrolase, imd gene product, exo-isomaltohydrolase (26 Jun 1999) |
| glucan endo-1,3-beta-d-glucosidase | <enzyme> An enzyme that hydrolyzes 1,3-beta-d-glucosidic linkages in 1,3-beta-d-glucans including laminarin, paramylon, and pachyman. Chemical name: 1,3-beta-D-Glucan glucanohydrolase Registry number: EC 3.2.1.39 (12 Dec 1998) |
| glucan synthase | <enzyme> Do not confuse with EC 2.4.1.34, which is 1,3-beta-glucan synthase or EC 2.4.1.12 which is 1,4-beta-glucan synthase Registry number: EC 2.4.1.- (26 Jun 1999) |
| glucan-1,4-glucosidase | <enzyme> An enzyme which removes the last 1,4-linked alpha-D- glucose residue from the nonreducing end of a long chain (or polymer) of such residues, making abeta-D-glucose molecule out of it in the process. (09 Oct 1997) |
| RNA, transfer, glu | A transfer RNA which is specific for carrying glutamic acid to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
