Retinol Retinol, also called vitamin A1, is a fat-soluble vitamin in the vitamin A family that is found in food and used as a dietary supplement. [2] Retinol or other forms of vitamin A are needed for vision, cellular development, maintenance of skin and mucous membranes, immune function and reproductive development. [2]

Vitamin B6 Chemical Structure
Publisher Summary. This chapter discusses the chemistry and physiology of vitamin A. Chemical work on vitamin A depends on the establishment of biological activity. In the preparation of vitamin A concentrates by extraction from fish liver oils, the distribution of the vitamin can be adequately checked by determination of the ultraviolet.
