carbon chain in their acyl moieties. The promoting action of N-acylaminoacids was not influenced by the presence of N-ethylmaleimide or ouabain. The promoting potencies of N-acylaminoacids were depressed in the presence of calcium chloride in the rectal loop. The contribution of the calcium ion sequestration capacity of N-acylaminoacids to their promoting efficacies is discussed.
