5.1 Definition and classification. Vitamins are a heterogeneous group of organic compounds essential for the growth and maintenance of animal life. The majority of vitamins are not synthesized by the animal body or at a rate sufficient to meet the animals needs.
Natural retinoids are present in all living organisms, either as preformed vitamin A or as carotenoids, and are required for biological processes such as vision and cellular growth. A major biologic function of vitamin A (as the metabolite retinal) is in the visual cycle. Research also suggests that vitamin A may reduce death from measles, prevent some types of cancer, aid in growth and development, and improve immune function.
