'Breaking Down Vitamin Compounds'

'Vitamin A\nVitamin A is a group of unsaturated nutritional original compounds, that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids, among which beta-carotene is the nearly in-chief(postnominal). Vitamin A has multiple functions: it is important for maturement and development, for the attention of the immune corpse and good fantasy. Vitamin A is needed by the retina of the eye in the turn of retinal, which combines with protein opsin to machinate rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and likeness vision. Vitamin A in addition functions in a very several(predicate) role as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth factor for epithelial and opposite cubicles.\nVitamin A is involved in immune function, vision, reproduction, and cellular communication [1,4,5]. Vitamin A is minute for vision as an inseparable component of rhodo psin, a protein that absorbs light in the retinal receptors, and because it supports the practice differentiation and go of the conjunctival membranes and cornea [2-4]. Vitamin A also supports cell growth and differentiation, playacting a critical role in the normal shaping and maintenance of the heart, lungs, kidneys, and other organs.\n- Molecular weighting: 286.4516 [g/mol]\n- Molecular radiation pattern: C20H30O\n- Boiling intimate: 137-138 deg C at 1X10-6 mm Hg\n- Melting stratum: 62-64 deg C\n- Solubilities: a lot in fat-soluble in water or glycerol; soluble in lordly alcohol, methanol, chloroform, ether, fats and oils.

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