Vitamin A Acetate 500,000IU
Introduce:
Vitamin A is a group of unsaturated nutritional organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the most important.
Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.
Vitamin A is needed by the retina of the eye in the form of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule, that is necessary for both low-light (scotopic vision) and color vision.
Vitamin A also functions in a very different role as an irreversibly oxidized form of retinol known as retinoic acid, which is an important hormone-like growth factor for epithelial and other cells.
