| glycosidase | <enzyme> General and imprecise term for an enzyme that breaks up and degrades complex sugar subunits of a polysaccharide such as starch or sucrose into simple ones, such as glucose or fructose. Widely used in food processing. It may distinguish between alpha and beta links but is not very substrate specific. (13 Nov 1997) |
| glycosidases | A class of hydrolytic enzymes that act on glycosides; alpha-glycosidases act on alpha-glycosidic linkages (e.g., alpha-amylase) while beta-glycosidases act on beta-glycosidic linkages (e.g., beta-glucosidase). (05 Mar 2000) |
| glycoside | <biochemistry> Any compound that contains a carbohydrate molecule (sugar), particularly any such natural product in plants, convertible, by hydrolytic cleavage, into sugar and a nonsugar component (aglycone) and named specifically for the sugar contained, as glucoside (glucose), pentoside (pentose), fructoside (fructose) etc. (18 Nov 1997) |
| glycoside hydrolases | <enzyme> Registry number: EC 3.2.1. (12 Dec 1998) |
| glycosides | Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (12 Dec 1998) |
| glycosidic | Referring to or denoting a glycoside or glycoside linkage. (05 Mar 2000) |
| glycosidic bond | <biochemistry> A bond between a sugar andanother organic molecule by way of anintervening nitrogen or oxygen atom. (09 Oct 1997) |
| glycosine | <chemistry> An organic base, C6H6N4, produced artificially as a white, crystalline powder, by the action of ammonia on glyoxal. Source: Websters Dictionary (01 Mar 1998) |
| glycosome | <cell biology> Microbody containing glycolytic enzymes, found in protozoa of the Kinetoplastida (e.g. Trypanosomes). Origin: Gr. Soma = body (18 Nov 1997) |
| glycosphingolipid | <biochemistry> Ceramide derivatives containing more than one sugar residue. If sialic acid is present these are called gangliosides. (18 Nov 1997) |
| glycosphingolipid beta1-3-N-acetylglucosaminyltransferase | <enzyme> Involved in blood group i-antigensynthesis Registry number: EC 2.4.1.- Synonym: gsp(1-3)agtase, glycosphingolipid beta 3-glcnactase (26 Jun 1999) |
| glycosphingolipid beta1-6-N-acetylglucosaminyltransferase | <enzyme> Involved in blood group i-antigen synthesis Registry number: EC 2.4.1.- Synonym: gsp(1-6)agtase, glycosphingolipid beta 6-glcnactase (26 Jun 1999) |
| glycosphingolipids | Ceramides which contain one or more sugar moieties. (12 Dec 1998) |
| glycostatic | Indicating the property of certain extracts of the anterior hypophysis that permits the body to maintain its glycogen stores in muscle, liver, and other tissues. (05 Mar 2000) |
