DefinitionThis section has been translated automatically.

3-Dehydroretinol, also known as vitamin A2, is a derivative of the retinal (see vitamin A below). The molecule is characterized by an additional double bond between C3 and C4 compared to vitamin A1. The vitamin A component belonging to the vitamin A group has the molecular formula C20H28O and has only about 1/3 of the biological activity of retinol. 3-Dehydroretinol is mainly found in the retina, as well as in epithelial cells. It is also found in the liver of Fischer and amphibians.
