Breaking Down Vitamin Compounds

Vitamin A\nVitamin A is a group of unsaturated nutritionary organic compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the most of import. Vitamin A has nonuple functions: it is important for growth and development, for the tutelage of the immune system and levelheaded vision. Vitamin A is needed by the retina of the eye in the public figure of retinal, which combines with protein opsin to form rhodopsin, the get-absorbing molecule needful for both low-light (scotopic vision) and color vision. Vitamin A also functions in a very different share as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth factor for epithelial and other cubicles.\nVitamin A is touch in immune function, vision, reproduction, and cellular communication [1,4,5]. Vitamin A is small for vision as an ingrained component of rhodopsin, a protein that absorbs light in the reti nal receptors, and because it supports the public 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 concern of the heart, lungs, kidneys, and other organs.\n- Molecular incubus: 286.4516 [g/mol]\n- Molecular Formula: C20H30O\n- simmering Point: 137-138 deg C at 1X10-6 mm Hg\n- dissolve Point: 62-64 deg C\n- soubilities: very much in fat-soluble in water system or glycerol; soluble in absolute alcohol, methanol, chloroform, ether, fats and oils.

In humans, the most important compounds in this group are vitamin D3 (also know as cholecalciferol) and vitamin D2 (ergocalciferol). Cholecalciferol and ergocalciferol can...
