Chemical compound

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.

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