The chemical reactions and pathways resulting in the formation of any of the vitamin A compounds, retinol, retinal (retinaldehyde) and retinoic acid. Animals can not synthesize vitamin A de novo, but form it through oxidative cleavage of carotenoids. The chemical reactions and pathways involving retinal, a compound that plays an important role in the visual process in most vertebrates. In the retina, retinal combines with opsins to form visual pigments. Retinal is one of the forms of vitamin A. The chemical reactions and pathways involving vitamins. Vitamin is a general term for a number of unrelated organic substances that occur in many foods in small amounts and that are necessary in trace amounts for the normal metabolic functioning of the body. Vitamins may be water-soluble or fat-soluble and usually serve as components of coenzyme systems. The chemical reactions and pathways involving of any of a diverse group of vitamins that are soluble in organic solvents and relatively insoluble in water. The chemical reactions and pathways involving retinoic acid, one of the three components that makes up vitamin A. The chemical reactions and pathways involving any of the vitamin A compounds, retinol, retinal (retinaldehyde) and retinoic acid, all of which are derivatives of beta-carotene. The chemical reactions and pathways involving retinol, one of the three compounds that makes up vitamin A. The chemical reactions and pathways involving lipids, as carried out by individual cells. The chemical reactions and pathways involving isoprenoid compounds, isoprene (2-methylbuta-1,3-diene) or compounds containing or derived from linked isoprene (3-methyl-2-butenylene) residues.
