| glyco- | Combining form denoting relationship to sugars (e.g., glycogen), or to glycine (e.g., glyocholate). See: gluco-. Origin: G. Glykys, sweet (05 Mar 2000) |

| glycobiarsol | Oxo(hydrogen N-glycoloylarsanilato)bismuth;a pentavalent arsenical containing bismuth; used in the treatment of milder forms of intestinal amoebiasis or as subsequent therapy. (05 Mar 2000) |
| glycobiology | <study> The study of sugars and their role in biology. (14 Nov 1997) |
| glycocalyx | <cell biology> The region, seen by electron microscopy, external to the outer dense line of the plasmalemma that appears to be rich in glycosidic compounds such as proteoglycans and glycoproteins. Since these molecules are often Integral membrane proteins and may be denatured by the processes of fixation for electron microscopy, it might be better to avoid the term or to refer to membrane glycoproteins or to proteoglycans associated with the cell surface.

| glycochenodeoxycholic acid | <chemical> N-(3 alpha,7 alpha-dihydroxy-5 beta-cholan-24-oyl)glycine. A bile salt formed in the liver from chenodeoxycholate and glycine, usually as the sodium salt. It acts as a detergent to solubilise fats for absorption and is itself absorbed. It is a cholagogue and choleretic. Pharmacological action: cholagogues and choleretics. Chemical name: Glycine, N-((3alpha,5beta,7alpha)-3,7-dihydroxy-24-oxocholan-24-yl)- (12 Dec 1998) |
| glycocholate | <physiology> A salt of glycocholic acid; as, sodium glycocholate. Origin: Glycocoll + cholic. Source: Websters Dictionary (01 Mar 1998) |
| glycocholate sodium | A normal constituent of bile of man and herbivores; glycocholate sodium from herbivores is purified and used as a choleretic and cholagogue. (05 Mar 2000) |
| glycocholic | <physiology> Pertaining to, or composed of, glycocoll and cholic acid. <physiology> Glycocholic acid, a conjugate acid, composed of glycocoll and cholic acid, present in bile in the form of a sodium salt. The acid commonly forms a resinous mass, but can be crystallized in long, white needles. Source: Websters Dictionary (01 Mar 1998) |
| glycocholic acid | <chemical> N-cholylglycine. Bile salt, conjugate of cholate and glycine, usually as the sodium salt. It acts as a detergent to solubilise fats for absorption and is itself absorbed. It is used as a cholagogue and choleretic. Pharmacological action: cholagogues and choleretics. Chemical name: Glycine, N-((3alpha,5beta,7alpha,12alpha)-3,7,12-trihydroxy-24-oxocholan-24-yl)- (12 Dec 1998) |
| glycocin | <physiology> Same as Glycocoll. Origin: Glycocoll + -in. Source: Websters Dictionary (01 Mar 1998) |
| glycocoll | <physiology> A crystalline, nitrogenous substance, with a sweet taste, formed from hippuric acid by boiling with hydrochloric acid, and present in bile united with cholic acid. It is also formed from gelatin by decomposition with acids. Chemically, it is amido-acetic acid. Synonym: glycin, and glycocin. Origin: Gr. Glykys sweet + kolla glue.

| glycoconjugates | Carbohydrates covalently linked to a nonsugar moiety (lipids or proteins). The major glycoconjugates are glycoproteins, glycopeptides, peptidoglycans, glycolipids, and lipopolysaccharides. (12 Dec 1998) |
| glycocorticoid | <pharmacology> Corticosteroid substances (drugs or hormones) that are involved in carbohydrate metabolism by promoting gluconeogenesis and the formation of glycogen at the expense of lipid and protein synthesis. They are steroid based and possess anti-inflammatory and immunosuppressive properties. Glucocorticoids are also produced normally by the adrenal cortex and provide for the response to stress. Examples include: prednisolone, methylprednisolone, hydrocortisone, betamethasone and dexamethasone. (29 Sep 1997) |
| glycocyamine | HN==C(NH2)NH-CH2COOH; 2-guanidinoacetic acid;formed by the transfer of the amidine group from l-arginine to glycine. Synonym: glucocyamine. (05 Mar 2000) |
| glycodeoxycholic acid | <chemical> N-(3 alpha,12 alpha-dihydroxy-5 beta-cholan-24-oyl)glycine. A bile salt formed in the liver by conjugation of deoxycholate with glycine, usually as the sodium salt. It acts as a detergent to solubilise fats for absorption and is itself absorbed. It is used as a cholagogue and choleretic. Pharmacological action: cholagogues and choleretics. Chemical name: Glycine, N-((3alpha,5beta,12alpha)-3,12-dihydroxy-24-oxocholan-24-yl)- (12 Dec 1998) |
