Vitamin A is a fat-soluble vitamin and an organic compound with the chemical formula C20H30O. It is stable to heat, acid, and alkali, and is easily oxidized. Ultraviolet rays can promote its oxidative destruction. Vitamin A includes A1 and A2, and A1 is retinol. Vitamin A2 is 3-dehydroretinol, and its physiological activity is 40% of that of vitamin A1. Vitamin A has various physiological functions such as promoting growth and reproduction, maintaining bone, epithelial tissue, vision and normal secretion of mucosal epithelium, and vitamin A and its analogues can prevent precancerous lesions. When lacking, it manifests as growth retardation and decreased dark adaptation ability to form night blindness. Due to dryness, desquamation, hyperkeratosis, and decreased lacrimal gland secretion of the epidermis and mucosal epithelial cells, dry eye disease occurs. In severe cases, corneal softening, perforation, and blindness occur. Respiratory epithelial cells keratinize and lose their cilia, reducing resistance to infection. The recommended vitamin A intake (RNI) for adults in my country is 800 μg retinol active equivalent per day for men, and 700 μg retinol active equivalent per day for women. Foods rich in vitamin A include poultry, livestock liver, egg yolk, milk powder, Carotene can be converted into vitamin A in the small intestinal mucosa, red, yellow and dark green vegetables, and fruits contain more carotene.
