Vitamin A is a fat soluble vitamin, an organic compound with the chemical formula C20H30O. It is stable to heat, acid, and alkali, and is easily oxidized. Ultraviolet radiation can promote its oxidative damage. Vitamin A includes A1 and A2, with A1 being retinol. Vitamin A2, also known as 3-dehydroretinol, has a physiological activity that is 40% of that of vitamin A1. [1]
Vitamin A plays an important role in maintaining vision, promoting growth and development, maintaining epithelial tissue health, enhancing immune function, and can inhibit certain precancerous lesions. Lack of vitamin A may lead to growth retardation, night blindness, dry eye syndrome, corneal softening, dry keratinization of the skin, and reduced respiratory resistance, increasing the risk of infection.

Application&Function

Vitamin A is not a single compound, but a series of retinol derivatives including retinol, retinaldehyde, retinic acid, retinyl acetate, and retinyl palmitate. Their molecular structures are shown in the figure "Molecular Structure of Vitamin A. Vitamin A only exists in animal bodies, and is abundant in fish, especially fish liver oil. Plants do not contain vitamin A, but many vegetables and fruits contain vitamin A precursor - carotenoids, which can be broken down into vitamin A in the small intestine. One molecule of beta carotene can be broken down into two molecules of vitamin A, while one molecule of A-carotene or gamma carotene can only produce one molecule of vitamin A
