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.
