| lactate | Important as the terminal product of anaerobic glycolysis. Accumulation of lactate in tissues is responsible for the so called oxygen debt. (18 Nov 1997) |
|---|---|
| lactate 2-mono-oxygenase | A flavoprotein oxidoreductase catalyzing oxidation (with O2) of l-lactate to acetate plus CO2 and water. Synonym: lactic acid oxidative decarboxylase. (05 Mar 2000) |
| lactate-2-sulfate sulfatase | <enzyme> Shows no activity for (l)-isomer Registry number: EC 3.1.6.- Synonym: d-lactate-2-sulfate sulfatase, d-lactate-2-sulfatase (26 Jun 1999) |
| lactate dehydratase | <enzyme> From cell extracts of clostridium propionicum; catalyses the dehydration of (r)-lactate to acrylate Registry number: EC 4.2.1.54 Synonym: lactyl CoA dehydratase, lactyl coenzyme a dehydratase, lactoyl-CoA dehydratase (26 Jun 1999) |
| lactate dehydrogenase | <enzyme> An enzyme with 5 forms: LDH-1 is in the heart, its blood level can rise when heart muscle is damaged. Other forms can be found in the liver, brain, kidney, skeletal muscle and bone. A useful blood test in the evaluation of many disease processes, including heart attack, liver disease, muscular dystrophy and bone disease. (27 Sep 1997) |
| lactate dehydrogenase isoenzymes | <enzyme> Registry number: EC 1.1.1.- (12 Dec 1998) |
| lactate dehydrogenase virus | A species of RNA virus, probably an arterivirus, occurring in a number of transplantable mouse tumours. Infected mice have permanently elevated serum levels of lactate dehydrogenase. (12 Dec 1998) |
| lactate level | A test that measures the amount of lactic acid in the blood. Lactic acid is an intermediate product of carbohydrate metabolism and is derived mainly from muscle cells and red blood cells. Exercise will normally raise lactic acid levels. Conditions of oxygen deprivation (for example shock, heart failure, lung disease) will trigger anaerobic metabolism within muscle tissue resulting in lactic acid build up in the tissues. Normal lactic acid levels are 4.5 to 19.8 mg/dl. (27 Sep 1997) |
