Vitamin Like Substances. History. Vitamin A. Vitamin A, also called retinol, is a fat-soluble vitamin that is readily destroyed upon exposure to heat, light, or air. The vitamin has a direct role in vision and is a component of a pigment present in the retina of the eye.

Vitamin D: An Overview. Vitamin D is a fat-soluble vitamin that is metabolized by the body by either sun (ultraviolet light) exposure or dietary intake. There are 2 molecules that make up vitamin D: ergocalciferol (D2) and cholecalciferol (D3). Ultraviolet B (UVB) radiation is absorbed by the skin and converts 7-dehydtocholesterol to vitamin D3. Vitamin D3 then goes into the capillary bed, where it binds to vitamin D binding protein (DBP).
