Definition of Somatotropin

Somatotropin: Growth hormone, a polypeptide containing 191 amino acids, produced by the anterior pituitary, the front section of the pituitary gland. It acts by stimulating the release of another hormone called somatomedin by the liver, thereby causing growth. Somatotropin is also known as somatropin.

Somatotropin is given to children with pituitary dwarfism (short stature due to underfunction of the anterior pituitary) to help them grow.
