3-hydroxyacyl-CoA dehydrogenase
In enzymology, a 3-hydroxyacyl-CoA dehydrogenase is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are -3-hydroxyacyl-CoA and NAD+, whereas its 3 products are 3-oxoacyl-CoA, NADH, and H+.
This enzyme belongs to the family of oxidoreductases, to be specific those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.Isozymes
In humans, the following genes encode proteins with 3-hydroxyacyl-CoA dehydrogenase activity:
3-Hydroxyacyl CoA dehydrogenase is classified as an oxidoreductase. It is involved in fatty acid metabolic processes. Specifically it catalyzes the third step of beta oxidation; the oxidation of L-3-hydroxyacyl CoA by NAD+. The reaction converts the hydroxyl group into a keto group.
The end product is 3-ketoacyl CoA.This enzyme participates in 8 metabolic pathways:
