In enzymology, a 3-hydroxyacyl-CoA dehydrogenase (EC 1.1.1.35) is an enzyme that catalyzes the chemical reaction
- (S)-3-hydroxyacyl-CoA + NAD+ 3-oxoacyl-CoA + NADH + H+
Thus, the two substrates of this enzyme are (S)-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[edit]
In humans, the following genes encode proteins with 3-hydroxyacyl-CoA dehydrogenase activity:
- HADH – Hydroxyacyl-Coenzyme A dehydrogenase
- HSD17B10 – 3-Hydroxyacyl-CoA dehydrogenase type-2
- EHHADH – Peroxisomal bifunctional enzyme
- HSD17B4 – Peroxisomal multifunctional enzyme type 2
Function[edit]
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.
Metabolic pathways[edit]
This enzyme participates in 8 metabolic pathways:
- fatty acid elongation in mitochondria
- fatty acid metabolism
- valine, leucine and isoleucine degradation
- lysine degradation
- tryptophan metabolism
- benzoate degradation via coa ligation
- butanoate metabolism
- caprolactam degradation
