Lactate Dehydrogenase (C0022917)

Definition (NCI_NCI-GLOSS) One of a group of enzymes found in the blood and other body tissues and involved in energy production in cells. An increased amount of lactate dehydrogenase in the blood may be a sign of tissue damage and some types of cancer or other diseases.
Definition (NCI) A family of homotetrameric cytoplasmic enzymes involved in the conversion of L-lactate and NAD to pyruvate and NADH in the final step of anaerobic glycolysis. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.
Definition (CSP) do not confuse with EC, EC, or EC, lactate dehydrogenase (cytochrome).
Definition (MSH) A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.
