Vitamins

For the various vitamins see vitamins. The word vitamin was coined in 1911 by the warsaw-born biochemist casimir funk (1884-1967). at the lister institute in london, funk isolated a substance that prevented nerve inflammation (neuritis) in chickens raised on a diet deficient in that substance. He named the substance vitamine because he believed it was necessary to life and it was a chemical amine. The e at the end was later removed when it was recognised that vitamins need not be amines. The letters (a, b, c and so on) were assigned to the vitamins in the order of their discovery. The one exception was vitamin k which was assigned its k from koagulation by the danish researcher henrik dam. Vitamins are required by numerous species, including ourselves for a balanced Diet. The actual vitamins that are required differ between species, as does the ability to synthesize protein within their own body.

More information pertaining to a [[balanced Vitamin diet is available in the developmental biology tutorial

...And I didn't say that "essential vitamins/cofactors" don't exist or don't play a role in the body, which is what you're implying that I said. As I'm sure you know, orthomolecular medicine involves the consumption of those compounds ...

Why do cells age?

... mean the neodarwinian religion that pervades EVERY area of science? You might want to learn some basic biology before citing essential cofactors (vitamins/minerals) as 'pseudoscience'.
