Insulin is a protein composed of two chains, an A chain (with 21 amino acids) and a B chain (with 30 amino acids), which are linked together by sulfur atoms. Insulin is derived from a 74-amino-acid prohormone molecule called proinsulin. Proinsulin is relatively inactive, and under normal conditions only a small amount of it is secreted. myocardial uptake of these substrates.1 The effects on myocardial uptake of amino acids were not investigated. Insulin promotes the uptake of amino acids by both heart and skeletal muscles under in vitro conditions.r" The same effects have been observed in vivo for skeletal muscles in normal subjects and in the clinical setting of surgical Through ATF4, insulin induces genes for amino acid synthesis and uptake, thereby increasing levels of intracellular amino acids. ATF4 is also regulated by the GAAC pathway, an evolutionarily ancient nutrient-sensing mechanism found in unicellular organisms that do not rely on hormones such as insulin to regulate metabolism.

A variety of individual amino acids, induce the release of insulin, but there are large differences among these amino acids in their capacities to stimulate its secretion. Increases in blood glucose observed during some of the amino-acid infusions cannot be the major cause of the increases in plasma insulin.

With insulin deficiency, amino acids are mobilized from muscle and transported to the liver. Insulin significantly increased the ileal uptake of valine, isoleucine, leucine, tyrosine, threonine, and serine from arterial blood: uptake of these amino acids was approximately doubled 45 min after the end of the insulin infusion. Insulin had no effect on glucose uptake or release. The insulin is secreted to stimulate protein synthesis--the uptake of amino acids into muscle cells--making them less available for gluconeogenesis. The glucagon is secreted to stimulate the uptake of amino acids into the cells of the liver for gluconeogenesis.

In addition to insulin's effect on entry of glucose into cells, it also stimulates the uptake of amino acids, again contributing to its overall anabolic effect. When insulin levels are low, as in the fasting state, the balance is pushed toward intracellular protein degradation. 1984-03-30 · Both the initial rate of amino acid uptake and the overall capacity for amino acid accumulation are increased.

In the present study no differences in amino acid uptake by the splanchnic region during insulin infusion was observed (Table 3), confirming that the periphery is the primary target of insulin on amino acid metabolism in humans.
