- 介绍: 活力定义:The amount of enzyme which will reduce one micromole of pyruvate to L-lactate per minute at 25°C in 0.1 M phosphate buffer at pH 7.0.
- 简介:LDH is a metabolic enzyme which is widely distributed in nature. Mammalian LDH exists as five tetrameric isozymes composed of combinations of two different subunits. The isozymes differ in physical, immunological and catalytic properties. LDH has a molecular weight of about 140,000.
- LDH is of clinical significance in that the serum level of certain isozymes suggests pathological changes in particular tissues. It is also used extensively for the determination of lactate and in coupled systems for detection of biological metabolites.
