home care health: Vitamin - Vitamin C Could Protect you Against Dementia MediMoon

A vitamin is an organic molecule (or a set of molecules contiguously combined chemically, i.e. vitamers) that is an indispensable micronutrient which an organism needs in little quantities for the proper on the go of its metabolism. essential nutrients cannot be synthesized in the organism, either at every or not in satisfactory quantities, and hence must be obtained through the diet. Vitamin C can be synthesized by some species but not by others; it is not a vitamin in the first instance but is in the second. The term vitamin does not augment the three other groups of essential nutrients: minerals, necessary fatty acids, and necessary amino acids. Most vitamins are not single molecules, but groups of united molecules called vitamers. For example, there are eight vitamers of vitamin E: four tocopherols and four tocotrienols. Some sources list fourteen vitamins, by including choline, but major health organizations list thirteen: vitamin A (as all-trans-retinol, all-trans-retinyl-esters, as without difficulty as all-trans-beta-carotene and new provitamin A carotenoids), vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic sour or folate), vitamin B12 (cobalamins), vitamin C (ascorbic acid), vitamin D (calciferols), vitamin E (tocopherols and tocotrienols), and vitamin K (phylloquinone and menaquinones).

Vitamins have diverse biochemical functions. Vitamin A acts as a regulator of cell and tissue layer and differentiation. Vitamin D provides a hormone-like function, amendable mineral metabolism for bones and additional organs. The B rarefied vitamins function as enzyme cofactors (coenzymes) or the precursors for them. Vitamins C and E statute as antioxidants. Both deficient and excess intake of a vitamin can potentially cause clinically significant illness, although excess intake of water-soluble vitamins is less likely to pull off so.

Before 1935, the unaccompanied source of vitamins was from food. If intake of vitamins was lacking, the upshot was vitamin nonattendance and consequent nonattendance diseases. Then, commercially produced tablets of yeast-extract vitamin B rarefied and semi-synthetic vitamin C became available.

This was followed in the 1950s by the growth production and promotion of vitamin supplements, including multivitamins, to prevent vitamin deficiencies in the general population. Governments mandated complement of vitamins to staple foods such as flour or milk, referred to as food fortification, to prevent deficiencies. Recommendations for folic prickly supplementation during pregnancy shortened risk of infant neural tube defects.

The term vitamin is derived from the word vitamine, which was coined in 1912 by Polish biochemist Casimir Funk, who without help a mysterious of micronutrients critical to life, all of which he presumed to be amines. subsequently this presumption was vanguard sure not to be true, the "e" was dropped from the name. all vitamins were discovered (identified) in the midst of 1913 and 1948.
