| 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) |
| glycosuria | <biochemistry, nephrology> The presence of glucose in the urine, especially the excretion of an abnormally large amount of sugar (glucose) in the urine, i.e., more than 1 gm. In 24 hours. Origin: Gr. Ouron = urine (18 Nov 1997) |
| glycosuria, renal | Glycosuria occurring when there is only the normal amount of sugar in the blood, due to inherited inability of the renal tubules to reabsorb glucose completely. (12 Dec 1998) |
| glycosyl | The radical resulting from detachment of the OH of the hemiacetal or hemiketal of a saccharide. Compare: glycoside. (05 Mar 2000) |
| glycosyl compound | The compound formed between a sugar and another organic substance in which the OH of the reducing (hemiacetal) group of the former is removed; e.g., the natural nucleosides, in which a heterocyclic N becomes linked directly to the C-1 of ribose (or deoxyribose) to yield ribosyl compounds. Compare: glycoside. (05 Mar 2000) |
| glycosyl group | <biochemistry> A radical chemical group on a larger molecule, derived from a sugar or starch molecule, which is attached to the rest of the larger molecule by way of a glycosidic bond. (09 Oct 1997) |
| glycosyl phosphatidyl inositol | gPI anchor |
| glycosylated alpha-amylase | <enzyme> Contains a single biantennary n-linked oligosaccharide that terminates with the structure fucalpha1,3(galbeta1,4)glcnac Registry number: EC 3.2.1.- Synonym: human glycosylated alpha-amylase (26 Jun 1999) |
| glycosylated haemoglobin | <biochemistry> A test which measures the amount of glucose-bound haemoglobin. As the blood glucose level increases the proportion of haemoglobin molecules which bind glucose increases with time. The measurement of glycosylated haemoglobin yields important information regarding how well a patients diabetes is being controlled. (27 Sep 1997) |
| glycosylated haemoglobin test | <investigation> A blood test that measures a person's average blood glucose (sugar) level for the 2- to 3-month period before the test. See: haemoglobin A1C. (09 Oct 1997) |
| glycosylation | <biochemistry> The process of adding sugar units such as in the addition of glycan chains to proteins. (18 Nov 1997) |
| glycosylation end products, advanced | Products derived from the nonenzymatic reaction of glucose and proteins in vivo that exhibit a yellow-brown pigmentation and an ability to participate in protein-protein cross-linking. These substances are involved in biological processes relating to protein turnover and it is believed that their excessive accumulation contributes to the chronic complications of diabetes mellitus. (12 Dec 1998) |
| glycosylceramidase | <enzyme> The enzyme hydrolyzing glycosyl-n-acylsphingosine to a sugar and n-acylsphingosine. It also catalyses the hydrolysis of phlorizin to phloretin and glucose. It is found in the intestinal brush border membrane often in conjunction with lactase. Chemical name: Glucosyl-N-acylsphingosine glycohydrolase Registry number: EC 3.2.1.62 (12 Dec 1998) |
| glycosylphosphatidylinositols | Compounds containing carbohydrate or glycosyl groups linked to phosphatidylinositols. They act to anchor proteins or polysaccharides to cell membranes. (12 Dec 1998) |
