Abstract

WIDE differences between the theoretically expected and experimentally obtained potencies of pure vitamin A as compared with β-carotene have led to a considerable amount of speculation1,2 on the possible manner of conversion of carotene into vitamin A in vivo. While there is no direct evidence in support of the postulated unsymmetrical fission of the provitamins, we felt that it might be of interest to study the extent of absorption of β-carotene by rats under the conditions of biological assay.
