The liver takes up 60 - 70% of the amino acids present in the portal vein. These amino acids, for the most part, are converted to glucose. After a pure protein meal, the increased levels of dietary amino acids reaching the pancreas stimulate the release of glucagon above fasting levels, thereby increasing amino acid uptake into the liver. However, insulin is also an important regulator of protein metabolism because this hormone and amino acids (AA) are key factors for the regulation of body protein mass . The main in vivo effect of insulin and AA on whole-body and skeletal muscle protein metabolism is to inhibit protein breakdown and to stimulate protein synthesis ( 3 – 5 ). We investigated the roles of insulin and amino acid (AA) in regulating milk production and the uptake of AA and blood flow (BF) by the mammary gland and hind-leg of goats (n = 4). During two periods, either saline or AA (65 g/d) was infused i.v.

Increase of DNA replication and protein synthesis via control of amino acid uptake; Modification of the activity of numerous enzymes. The actions of insulin (indirect and direct) on cells include: Stimulates the uptake of glucose – Insulin decreases blood glucose concentration by inducing intake of glucose by the cells. This is possible because Insulin causes the insertion of the GLUT4 transporter in the cell membranes of muscle and fat tissues which allows glucose to enter the cell. The major effects of insulin on muscle and adipose tissue are: (1) Carbohydrate metabolism: (a) it increases the rate of glucose transport across the cell membrane, (b) it increases the rate of glycolysis by increasing hexokinase and 6-phosphofructokinase activity, (c) it stimulates the rate of glyc … 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.

Attenuation of the uptake of neutral amino acids with a LAT inhibitor reduced insulin secretion and insulin content in Min6 cells, whereas overexpression of LAT1 increased insulin secretion. the luminal fluid [28].

Insulin uptake of amino acids

resulted in no inhibition of amino acid uptake (Table I). Insulin (0.4 unit per ml) stimulated uptake a-fold under these conditions and this stimulation was not impaired by puromycin. Quite different results were seen when the preincubation period was lengthened to 3 hours (Fig.

These amino acids, for the most part, are converted to glucose.

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 trauma.v!' Thereare, to our knowledge, no cor Blood flow was measured by dye dilution using p-amino-hippuric acid and was increased by 37% by infusion of insulin plus AA (P less than.05).

In addition to the phenylalanine on the N-terminus, two Leucine residues and acidic motifs on the COOH-terminus are believed to play a key role in the kinetics of endocytosis and exocytosis.
