Vitamin A has multiple functions: it is important for reaping and development, for the maintenance of the resistant system and good imagery. Vitamin A is needed by the retina of the marrow in the take a shit of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing molecule necessary for both(prenominal) low-light (scotopic vision) and color vision. Vitamin A similarly functions in a real different role as retinoic acid (an irreversibly change form of retinol), which is an important hormone-like developing factor for epithelial and opposite cells.\nVitamin A is involved in immune function, vision, reproduction, and cellular communicating [1,4,5].

Vitamin A also supports cell growth and differentiation, playing a critical role in the normal formation and maintenance of the heart, lungs, kidneys, and new(prenominal) organs.\n- molecular(a) Weight: 286.4516 [g/mol]\n- Molecular Formula: C20H30O\n- Boiling grade: 137-138 deg C at 1X10-6 mm Hg\n- Melting pane: 62-64 deg C\n- Solubilities: Practically indissoluble in water or glycerol; soluble in absolute alcohol, methanol, chloroform, ether, fats and oils.
