English: Tretionin is synthesized from Beta-carotene. The Beta-carotene is firstly cleaved into Beta-carotene 15-15’-monooxygenase through site 1 double bond oxidized to epoxide. The epoxide is attacked by water to form diol in site 1. NADH, as a reduction agent, reduce the alcohol group to aldehydes. Following with aldehyde dehydrogenase 1 family of enzymes (ALD 1), aldehydes are then reduced to tretionin (retinoic acid).
