Somatropin (HGH)
Mechanism of action
What Somatropin (HGH) does in the body — step by step.
Somatropin is recombinant human growth hormone (hGH), a 191-amino-acid protein that matches the body's own pituitary growth hormone in structure and action.
It binds to the growth hormone receptor and mediates its effects partly directly and partly via the release of IGF-1, predominantly in the liver.
Described effects include longitudinal growth (in childhood), protein synthesis, lipolysis and carbohydrate metabolism.
