A lactate dehydrogenase (LDH or LD) is an enzyme found in nearly all living cells (animals, plants, and prokaryotes).LDH catalyzes the conversion of pyruvate to lactate and back, as it converts NADH to NAD + and back.A dehydrogenase is an enzyme that transfers a hydride from one molecule to another. LDH exist in four distinct enzyme classes.This article is about the common NAD(P)-dependent L-lactate dehydrogenase.issue breakdown releases LDH, and therefore LDH can be measured as a surrogate for tissue breakdown, e.g. hemolysis. LDH is measured by the lactate dehydrogenase (LDH) test (also known as the LDH test or Lactic acid dehydrogenase test).
