3-Ketosteroid reductase

+ Save concept

In enzymology, a 3-keto-steroid reductase is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are 4alpha-methyl-5alpha-cholest-7-en-3beta-ol and NADP+, whereas its 3 products are 4alpha-methyl-5alpha-cholest-7-en-3-one, NADPH, and H+. [1]

Catalysis

Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalysthttp://goldbook.iupac.org/C00876.html, which is not consumed in the catalyzed reaction and can continue to act repeatedly.

Nicotinamide adenine dinucleotide phosphate

Nicotinamide adenine dinucleotide phosphate, abbreviated NADP or, in older notation, TPN (triphosphopyridine nucleotide), is a cofactor used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent.

Oxidoreductase

In biochemistry, an oxidoreductase is an enzyme that catalyzes the transfer of electrons from one molecule, the reductant, also called the electron donor, to another, the oxidant, also called the electron acceptor.
