Vitamin A alike functions in a truly different occasion as retinoic acid (an irreversibly oxidize form of retinol), which is an important hormone-like appendage operator for epithelial and new(prenominal) cells.\nVitamin A is have-to doe with in immune function, vision, reproduction, and cellular dialogue [1,4,5]. Vitamin A is full of life for vision as an essential parting of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the prevalent preeminence and functioning of the conjunctival membranes and cornea [2-4]. Vitamin A also supports cell growth and differentiation, playing a critical billet in the normal formation and maintenance of the heart, lungs, kidneys, and other organs.\n- molecular Weight: 286.4516 [g/mol]\n- molecular(a) Formula: C20H30O\n- boiling Point: 137-138 deg C at 1X10-6 mm Hg\n- thaw Point: 62-64 deg C\n- solubilities: Practically non- body of water-soluble in water or glycerine; soluble in absolute alcohol, m neutral spirits, chloroform, ether, fats and oils.
