Further Studies of the Conversion of β-Carotene to Vitamin A in the Intestine

Abstract

We have already reported in full some of our findings on the formation of vitamin A in the intestine (Thompson, Ganguly & Kon, 1949). The present paper deals with further evidence, in particular that derived from observations on the appearance of vitamin A in the portal and systemic circulations of pigs and in the mesenteric lymph of pigs and rats.
