| malabsorption syndrome | <syndrome> A variety of conditions in which digestion and absorption in the small intestine are impaired. Multiple causes including lymphoma, amyloid and other infiltrations, Crohn's disease, gluten sensitive enteropathy and the sprue syndrome in which the villi atrophy for unknown reasons. (18 Nov 1997) |
|---|---|
| methionine malabsorption syndrome | <syndrome> An inherited disorder in which there is an inability to absorb l-methionine from the gut. (05 Mar 2000) |
| carbohydrate-deficient glycoprotein syndrome | <syndrome> An inborn error of carbohydrate metabolism manifesting as a genetic multisystem disorder of autosomal recessive inheritance. A predominant feature is severe central and peripheral nervous system involvement resulting in psychomotor retardation, seizures, cerebellar ataxia, and other symptoms which include growth retardation, retinitis pigmentosa, hypothyroidism, and fatty liver. The notable biochemical feature is the deficiency of a large number of blood glycoproteins and decreased activities of various blood coagulation factors. (12 Dec 1998) |
| malabsorption | <gastroenterology> Impaired intestinal absorption of nutrients. (18 Nov 1997) |
| malabsorption syndromes | General term for syndromes of malnutrition due to failure of normal intestinal absorption of nutrients. (12 Dec 1998) |
| intestinal malabsorption | <gastroenterology> The inadequate absorption of nutrients from the small intestine. This can result in loss of weight and abnormal appearing stools. Malabsorption can be caused by lesions of the small intestine, amyloidosis, lack of digestive enzymes (for example lactose intolerance) or bile salts or surgical operations. (10 Jan 1998) |
| antigens, tumour-associated, carbohydrate | Carbohydrate antigens expressed by malignant tissue. They are useful as tumour markers and are measured in the serum by means of a radioimmunoassay employing monoclonal antibodies. (12 Dec 1998) |
| carbohydrate | <biochemistry> Very abundant compounds, usually an aldehyde or ketone derivative of a polyhydric alcohol, particularly of the pentahydric and hexahydric alcohols. They are so named because the hydrogen and oxygen are usually in the proportion to form water with the general formula Cn(H2O)n. The most important carbohydrates are the starches, sugars, celluloses and gums. They are classified into mono, di, tri, poly and heterosaccharides. The smallest are monosaccharides like glucose whereas polysaccharides such as starch, cellulose or glycogen can be large and indeterminate in length. (08 Oct 1997) |
| carbohydrate conformation | The characteristic 3-dimensional shape of a carbohydrate. (12 Dec 1998) |
| carbohydrate dehydrogenases | <enzyme> Reversibly catalyze the oxidation of a hydroxyl group of carbohydrates to form a keto sugar, aldehyde or lactone. Any acceptor except molecular oxygen is permitted. Registry number: EC 1.1. (12 Dec 1998) |
| carbohydrate epimerases | <enzyme> Enzymes that catalyze the epimerization of chiral centres within carbohydrates or their derivatives. Registry number: EC 5.1.3 (12 Dec 1998) |
| carbohydrate-induced hyperlipaemia | type III familial hyperlipoproteinaemia, type IV familial hyperlipoproteinaemia |
| carbohydrate loading | A procedure popular with long-distance runners and other athletes of filling muscles with a large glycogen pool prior to an athletic event; often, the athlete consumes very few carbohydrates for three days followed by a largely carbohydrate diet for the last three days before the event. (05 Mar 2000) |
| carbohydrate metabolism | <biochemistry> The breakdown of starches and sugars into smaller units that can be used by the body for energy. (27 Sep 1997) |
| carbohydrate sequence | The sequence of carbohydrates within polysaccharides, glycoproteins, and glycolipids. (12 Dec 1998) |
