| membrane transport | <cell biology> The transfer of a substance from one side of a plasma membrane to the other, in a specific direction and at a rate faster than diffusion alone. See: active transport. (18 Nov 1997) |
| apical plasma membrane | <cell biology> The term used for the cell membrane on the apical (inner or upper) surface of transporting epithelial cells. This region of the cell membrane is separated, in vertebrates, from the baso lateral membrane by a ring of tight junctions that prevents free mixing of membrane proteins from these two domains. (18 Nov 1997) |
| basolateral plasma membrane | <cell biology> The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes). (18 Nov 1997) |
| plasma membrane | <cell biology> The external, limiting lipid bilayer membrane of cells. (31 Dec 1997) |
| carnitine | <biochemistry> _ Hydroxy _ trimethyl aminobutyric acid. Compound that transports long chain fatty acids across the inner mitochondrial membrane in the form of acyl carnitine. Sometimes referred to as Vitamin Bt or Vitamin B7. (18 Nov 1997) |
| carnitine acyltransferases | <enzyme> Acyltransferases in the inner mitochondrial membrane that catalyze the reversible transfer of acyl groups from acyl-CoA to l-carnitine and thereby mediate the transport of activated fatty acids through that membrane. Registry number: EC 2.3.1.- (12 Dec 1998) |
| carnitine amidase | <enzyme> Hydrolyzes l-carnitine amide steroselectively Registry number: EC 3.5.1.- (26 Jun 1999) |
| carnitine coenzyme A ligase | <enzyme> Caic protein isolated from e. Coli Registry number: EC 6.2.1.- Synonym: carnitine CoA ligase, crotonobetaine CoA ligase, caic gene product (26 Jun 1999) |
| carnitine dehydratase | <enzyme> From E coli; catalyses the reversible dehydration of (l)-carnitine forming crotonobetaine Registry number: EC 4.2.1.- Synonym: caib protein, caib gene product (26 Jun 1999) |
| carnitine o-acetyltransferase | <enzyme> An enzyme that catalyses the formation of o-acetylcarnitine from acetyl-CoA plus carnitine. Chemical name: Acetyl-CoA:carnitine O-acetyltransferase Registry number: EC 2.3.1.7 (12 Dec 1998) |
| carnitine o-palmitoyltransferase | <enzyme> An enzyme that catalyses reversibly the conversion of palmitoyl-CoA to palmitoylcarnitine in the inner mitochondrial membrane. Chemical name: Palmitoyl-CoA:L-carnitine O-palmitoyltransferase Registry number: EC 2.3.1.21 (12 Dec 1998) |
| carnitine palmitoyltransferase | <enzyme> An enzyme that reversibly forms acylcarnitines and coenzyme A from carnitine and acylcoenzyme A (often, palmitoyl-CoA); important in fatty acid oxidation. Deficiency of isozyme I results in ketogenesis with hypoglycaemia; deficiency of isozyme II affects primarily skeletal muscle. (05 Mar 2000) |
| carnitine racemase | <enzyme> Homologous to enoyl hydratases and isomerases; converts d(+)-carnitine to l(-)-carnitine; isolated from e. Coli Registry number: EC 5.1.- Synonym: caid gene product (26 Jun 1999) |
| l-carnitine | <amino acid> Is a dipeptide - an amino acid made from two other aminos, methionine and lysine. It can be synthesised in the liver if sufficient amounts of lysine, B1, B6 and iron are available. Muscle and organ meat, fish and milk products are the best sources of carnitine in the diet. Carnitine has been shown to have a major role in the metabolism of fat and in the reduction of triglycerides by increasing fat utilisation. It transfers fatty acids across the membranes of the mitochondria where they can be utilised as sources of energy. It also increases the rate at which the liver uses fats. By preventing fatty build-up, this amino acid aids in weight loss and decreases the risk of heart disease. Carnitine has been shown to be deficient in hearts of patients who have died of acute myocardial infections. Muscular dystrophy and myotonic dystrophy have been shown to lead to carnitine loss in the urine and therefore higher requirements for it. Carnitine is stored primarily in the skeletal muscles and heart, where it is needed to transform fatty acids into energy for muscular activity. It is also concentrated in sperm and the brain. Many athletes have noted increased endurance and muscle building with carnitine supplementation. Deficiencies may increase symptoms of fatigue, angina, muscle weakness or confusion. A low level of Vitamin C will also result in apparent Carnitine deficiency. It is contraindicated for people with liver or kidney disease or diabetes It has proven helpful in improving lipid metabolism and reducing elevated total lipids, cholesterol and triglycerides in people with cardiac problems and diabetes, but should only be taken with medical supervision in these conditions.
