12 Alpha-hydroxysteroid dehydrogenase (EC 1.1.1.176) belongs to the family of oxidoreductases. More precisely, it is a member of the oxidoreductases that act on the CH-OH group of the electron donor with NAD+ (nicotinamide adenine dinucleotide) or NADP+ (nicotinamide adenine dinucleotide phosphate) as the electron acceptor. In metabolism, 12 alpha-hydroxysteroid dehydrogenase degrades 12 alpha-hydroxy group of bile acids, as well as bile alcohols, into cholesterols. In enzymology, the enzyme catalyzes the oxidation of 3 alpha,7 alpha,12 alpha-trihydroxy-5 beta-cholanate and NADP+ into 3 alpha,7 alpha-dihydroxy-12-oxo-5 beta-cholanate with NADPH and H+. The systematic name of this enzyme class is 12 alpha-hydroxysteroid:NADP+ 12-oxidoreductase, and it was also named as:
12 Alpha-hydroxysteroid dehydrogenase is NAD-dependent and active against conjugated and unconjugated forms of bile salts. It is involved in the metabolism of bile salts and cholesterol. Cholesterol is the essential component of cell membranes structure to maintain its integrity and fluidity, and the precursor for the steroid hormones and bile acids biosynthesis. In addition, the 12alpha-hydroxysteroid dehydrogenase, which is heat labile, together with 3alpha-hydroxysteroid dehydrogenases, which is heat stable, could be applied in the spectrophotometric quantification of bile salts.
