Vitamin A Molecular Structure. Humans can synthesize vitamin A from the precursor molecule beta carotene. Chemical structure of Vitamin A or Retinol. Currently there are 13 recognised vitamins. Vitamins are an important part of our diet but you probably havent given a great deal of thought to their chemical structures.
Computed by Cactvs 34611 PubChem release 20190618 Rotatable Bond Count. Vitamin A or retinolhas a structure depicted to the right. Retinol is the immediate precursor to two important active metabolites. The four tocopherols have a saturated phytyl side chain while tocotrienols have an unsaturated isoprenyl side chain. The fat soluble vitamins vitamins A D E and K can be stored by our bodies in the liver or in fatty tissues.

Below is a brief discussion and a look at the evidence for taking vitamin. Vitamin E alpha tocopherol is a fat soluble vitamin and potent antioxidant that is believed to be important in protecting cells from oxidative stress regulating immune function maintaining endothelial cell integrity and balancing normal coagulationThere is no evidence that vitamin E in physiologic or even super-physiologic high doses causes liver injury or jaundice. The four tocopherols have a saturated phytyl side chain while tocotrienols have an unsaturated isoprenyl side chain. It is toxic in high doses.
