Description:
Vitamin A is a fat-soluble vitamin, organic compound, chemical formula is C20H30O, stable to heat, acid and base, easy to be oxidized, ultraviolet light can promote its oxidative damage. Vitamin A has many physiological functions, such as promoting growth, reproduction, maintaining bone, epithelial tissue, vision and normal secretion of mucosal epithelium, etc. Vitamin A and its analogues have the effect of preventing precancerous lesions. When lacking, it is manifested as growth retardation, dark adaptation and the formation of night blindness. Due to epidermal and mucosal epithelial cells drying, desquamation, excessive keratosis, reduced secretion of lacrimal glands, resulting in dry eye disease, severe corneal malacia, perforation and blindness. Respiratory epithelial cells become keratinized and lose cilia, making them vulnerable to infection.
