Where is the source of all vitamin A in?
Vitamin A is an unsaturated cyclic alcohol. It is synthesezed by at least three separate processes.
It has been concentrated and isolated from the non-saponiflable to be present in fish oil, both in the free alcohol and in the ester form. The source of all vitamin A is in the carotenoid pigments, the yellow-coloured, compounds occurring in all chlorophyll-containing plants.
In pure form it is a pale yellow oil, soluble in fat solvents, having an ultra-violet absorption spectrum. The ester forms of the vitamin have been found to possess greater stability than the free alcohol.
