Long Chain Human Insulin Like Growth Factor 1 R3 (IGF1LR3)

Long chain human insulin-like growth factor (IGF-1 LR3) is a kind of protein which has 83 amino acids. Long IGF-1 R3 has many functions, such increasing protein synthesis, increasing the RNA synthesis, promoting fat metabolism and glucose transport. Therefore in bodybuilders and athletes, the Long IGF-1 R3 can promote the muscle cell become large and transform the fat into energy.Hypertrophy is what occurs during weight training and steroid use, it is simply an increase in the size of muscle cells.

Growth of the fetal heart involves cardiomyocyte enlargement, division, and maturation. Insulin-like growth factor-1 (IGF-1) is implicated in many aspects of growth and is likely to be important in developmental heart growth. IGF-1 stimulates the IGF-1 receptor (IGF1R) and downstream signaling pathways, including extracellular signal-regulated kinase (ERK) and phosphoinositol-3 kinase (PI3K).
