BACKGROUND Biocytin is an important end product of intraluminal digestion of dietary protein-bound biotin. Limited studies are available regarding the ability of the small intestine to transport biocytin and about the mechanism involved. The aim of the present study was to delineate these issues. METHODS Transport of [3H]-biocytin was examined using everted sacs from rat intestine. RESULTS Mucosal-to-serosal transport of low (0.022 mumol/L) and high (5 mumol/L) concentrations of biocytin… CONTINUE READING
