glycoprotein (redirected from Glycoprotien)

glycoprotein /gly·co·pro·tein/ (-pro´tēn) a conjugated protein covalently linked to one or more carbohydrate groups; technically those with less than 4 per cent carbohydrate but often expanded to include the mucoproteins and proteoglycans.

[glī′kōprō′tēn]

Etymology: Gk, glykys, sweet, proteios, first rank

any of the large group of conjugated proteins in which the nonprotein substance is a carbohydrate. These include the mucins, the mucoids, and the chondroproteins.

glycoprotein [gli″ko-pro´tēn]

any of a class of conjugated proteins consisting of a compound of protein with a carbohydrate group.

α1-acid glycoprotein an acute phase protein found in blood plasma, an indicator of tissue necrosis and inflammation. Called also orosomucoid.

P-glycoprotein a cell-surface protein occurring normally in the colon, small intestine, adrenal glands, kidney, and liver, and also expressed by tumor cells. It is a modulator of multidrug resistance, mediating the transport of antineoplastic agents out of tumor cells.

variable surface glycoprotein any of several glycoproteins that form the antigenic protein coating of Trypanosoma brucei. The organisms contain numerous genes encoding hundreds of such glycoproteins and, by expressing individual ones successively, evade the immune system of the host.

glycoprotein,

n a large group of conjugated proteins in which the nonprotein substance is a carbohydrate. These include the mucins, the mucoids, and the chondroproteins.

glycoprotein deficiency

an inherited disorder in dogs in which there is defective phagocytic function. Affected dogs have a marked, persistent neutrophilia and are susceptible to infections.

glycoprotein

One of a group of conjugated proteins formed by a protein and a carbohydrate, the most important being the mucins (as found in the lens capsule, vitreous humour) and mucoids (as found in bones, cartilage, tendons).
