Effect of parenterally injected insulin and its composite sulpho-A- and B-chains on the rate of protein synthesis by the organs of the rat was investigated. It has been shown that insulin accelerates the incorporation of I-C14-glycine into proteins of the liver, kidneys, pancreas, spleen, sceletal muscules, thyroid gland, thymus and adrenal glands but does not influence this process in the cardiac muscle and diaphragm. A- and B-chains also activated protein metabolism in some organs, but despite some specificity of their action its extent was more limited as compared to that of insulin.
