title: Competitive inhibition and exchange transport between arginine and lysine in the process of absorption from the caecum in pigs.
abstract: Competitive inhibition and exchange transport between arginine and lysine in the process of absorption from the caecum in pigs. Acta Physiol. Pol., 1978, 29 (2): 161--165. Arginine competes with lysine in the process of transport across the mucosal epithelium of the pig caecum, and the ability of arginine absorption is much greater than that of lysine. Absorption of large amounts of arginine causes secretion of large amounts of lysine into the intestinal lumen in the process of primary active exchange transport. Lysine is better absorbed from solution containing no other amino acids than from solutions containing mixtures of amino acids. Basic amino acids (Arg, Lys, His) stimulate the absorption of serine and threonine from the caecum of pigs.
