Breaking Down Vitamin Compounds

Vitamin A\nVitamin A is a separate of unsaturated nutritional organic compounds, that includes retinol, retinene, retinoic panelling, and several(prenominal) provitamin A carotenoids, among which beta-carotene is the most all-important(a). Vitamin A has multiple functions: it is important for return and development, for the maintenance of the repellent system and good vision. Vitamin A is infallible by the retina of the eye in the stress of retinal, which combines with protein opsin to form rhodopsin, the light-absorbing tittle necessary for both low-light (scotopic vision) and disguise vision. Vitamin A as well as functions in a very antithetic authority as retinoic acid (an irreversibly oxidized form of retinol), which is an important hormone-like growth actor for epithelial and other cells.\nVitamin A is involved in immune function, vision, reproduction, and cellular communication [1,4,5]. Vitamin A is critical for vision as an essential component of rhodops in, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and performance of the conjunctival membranes and cornea [2-4]. Vitamin A also supports cell growth and differentiation, playacting a critical role in the normal organic law and maintenance of the heart, lungs, kidneys, and other organs.\n- molecular Weight: 286.4516 [g/mol]\n- Molecular law: C20H30O\n- Boiling Point: 137-138 deg C at 1X10-6 mm Hg\n- Melting Point: 62-64 deg C\n- Solubilities: Practically insoluble in water or glycerol; soluble in compulsory alcohol, mgrain alcohol, chloroform, ether, fats and oils. Sol in ethanol and acetone and benzene\n\nVitamin D\nVitamin D refers to a group of fat-soluble secosteroids responsible for enhancing intestinal engrossment of calcium, iron, magnesium,phosphate and zinc. In humans, the most important compounds in this group ar vitamin D3 (also known as cholecalciferol) and vitamin D2 ( viosterol). Cholecalciferol an d ergocalciferol can...
