Glycyrrhiza
The dried root of Glycyrrhiza glabra, known commercially as Spanish licorice. It is used as an ingredient of glycyrrhiza fluid extract and glycyrrhiza syrup, both of which are used as flavoring agents in compounding medicine. This substance has a weak aldosterone-like effect and may therefore increase blood pressure.

Glycosylphosphatidylinositol
A lipid in the plasma membrane of cells that anchors proteins on the cell’s surface. Some of the proteins held on the cell surface protect cells against attack by serum complement. Mutations that decrease or eliminate GPI are responsible for the destruction of blood cells by the complement system, which characterizes the disease called paroxysmal…

glycostatic
Acting to maintain the level of glucose in the body. An abnormal amount of glucose in the urine. Traces of sugar, particularly glucose, may occur in normal urine but are not detected by ordinary qualitative methods. The presence of a reducing sugar found during routine urinalysis is suggestive but not diagnostic of diabetes mellitus. It…

glycosphingolipids
A group of carbohydrate-containing fatty acid derivatives of ceramide. Three classes of these lipids are cerebrosides, gangliosides, and ceramide oligosaccharides. When the enzymes essential to the metabolism of these compounds are absent, the glycosphingolipids accumulate, particularly in the nervous system. Death is the usual outcome.

Glycosialorrhea
Excessive secretion of saliva containing glucose.
-
Glycophorin
A glycoprotein that spans the bilipid layer of the red blood cell membrane. The extracellular end attaches to oligosaccharide blood group antigens. This protein provides the conduit through which anions pass in and out of the red blood cell.

Glycopexis
The storage of glycogen in the liver.
-
Glycopeptide antibiotic
Any antibiotic composed of a short amino acid chain linked to a carbohydrate. Vancomycin and teicoplanin are glycopeptide antibiotics.
-
Glycopeptide
A chemical compound in which carbohydrate molecules are linked covalently to a short amino acid chain.
