Dehydroretinal Explained

Dehydroretinal (3,4-dehydroretinal) is a derivative metabolite of retinal belonging to the group of vitamin A2 as a retinaldehyde form, besides the endogenously present 3,4-dehydroretinol and 3,4-dehydroretinoic acid.[1] [2]

The livers of some freshwater fishes and some fish found in India contain a higher ratio of dehydroretinal to retinal than do other species.[3]
