Breaking Down Vitamin Compounds

Vitamin A\nVitamin 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 meaning(a). Vitamin A has fourfold functions: it is important for growth and development, for the guardianship of the immune system and reliable vision. Vitamin A is needed by the retina of the eye in the determine of retinal, which combines with protein opsin to form rhodopsin, the free-absorbing molecule inevitable for both low-light (scotopic vision) and color vision. Vitamin A also functions in a very different intent as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth factor for epithelial and other mobile phones.\nVitamin A is have-to doe with in immune function, vision, reproduction, and cellular communication [1,4,5]. Vitamin A is deprecative for vision as an natural component of rhodopsin, a protein that abs orbs light in the retinal receptors, and because it supports the conventionalism differentiation and functioning of the conjunctival membranes and cornea [2-4]. Vitamin A also supports cell growth and differentiation, playing a critical role in the normal formation and bread and butter of the heart, lungs, kidneys, and other organs.\n- Molecular pitch: 286.4516 [g/mol]\n- Molecular Formula: C20H30O\n- stewing Point: 137-138 deg C at 1X10-6 mm Hg\n- thawing Point: 62-64 deg C\n- sohubilities: lots insoluble in peeing or glycerol; soluble in absolute alcohol, methanol, chloroform, ether, fats and oils.
