Vitamin A,vitamin A foods,Vitamin A benefits

Vitamin A, in a specific metabolite form, is essential to the eye retina. This molecule which absorbs the light in the retina is absolutely needed for both color vision and scotopic. Vitamin A has a different role too.

It functions as a retinoic acid in oxidized form which is irreversible. It is a vital factor for other cells and epithelial to grow.

Ester is the major type of vitamin A found in foods which are of animal origin, primarily retinyl palmitate. In the small intestine, it is converted to alcohol.

The function of retinol form is to store the vitamin, which is then converted to its active visual aldehyde form, which is retinal.
The retinoic acid does not work in the essential parts of reproductive system and the retina as it contains only partial A vitamin activity. Retinoic acid is a metabolite which is synthesized irreversibly from vitamin A.
