title: [Effect of creatine and other phosphorylable amino compounds on the ileal absorption of Ca-45 in the rat].
abstract: Some carbohydrates which increase calcium absorption were phosphate acceptors. When administrated to adult Rat in ileal ligated loop, phosphorylable amino compounds such as creatine, L-aspartic and L-glutamic acids also increased calcium absorption; other effective compounds such as D- and L-lysine and D-alanine might be involved in reactions of phorphorylation. L-alanine, L- and D-valine and asparagine were ineffective in enhancing calcium absorption and were not phosphorylable. Injection of creatine into ileal loop induced the formation of its phosphorylated derivative. Absorption of the amino compound was not correlated with the fact that they were effective on calcium absorption.
