dehydrogenase Definition

an enzyme that accelerates the removal of hydrogen from metabolites and its transfer to other substances

an enzyme found especially in red blood cells that dehydrogenates glucose-6-phosphate in a glucose degradation pathway alternative to the Krebs cycle

any of a group of isoenzymes that catalyze reversibly the conversion of pyruvic acid to lactic acid —called also lactic dehydrogenase

an iron-containing flavoprotein enzyme that catalyzes often reversibly the dehydrogenation of succinic acid to fumaric acid in the Krebs cycle and that is widely distributed especially in animal tissues, bacteria, and yeast —called also succinic dehydrogenase
