Carnitine 3 dehydrogenase

In enzymology, a carnitine 3-dehydrogenase (EC 1.1.1.108) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are carnitine and NAD⁺, whereas its 3 products are 3-dehydrocarnitine, NADH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is carnitine:NAD⁺ 3-oxidoreductase.
