Vitamin A and the provitamin A carotenoids,due to the absence of the fat-soluble A in the diet. In the meantime it was discovered that green vegetables also possess fat-soluble A activity and in 1930 Moore provided evidence that carotene was converted to vitamin A in the body. The biochemical function of vitamin A in vision was established by Wald in 1935.

Vitamin D,e antirachitic properties, thus indicating the presence of two factors: factor A (or vitamin A) and the antirachitic factor, which they later termed ‘fat-soluble’ vitamin D. Zucker and co-workers in 1922 found that vitamin D was present in the unsaponifiable fraction of cod-liver oil, and suggested that it was closely related to cholesterol.

Physiological aspects of vitamin bioavailability,amin B.. This simple classification reflects to some extent the bioavailability of the vitamins, as the solubility affects their mode of intestinal absorption and their uptake by tissues. The solubility properties also have a direct bearing on the analytical methods employed in vitamin assays.
