| Description : |
Follicle-stimulating hormone (FSH) is a hormone found in humans and other animals. It is synthesized and secreted by gonadotrophs of the anterior pituitary gland. FSH is a glycoprotein. Each monomeric unit is a protein molecule with a sugar attached to it; two of these make the full, functional protein. The protein dimer contains 2 polypeptide units, labeled alpha and beta subunits. The alpha subunits contain 92 amino acids. The beta subunits vary. FSH has a beta subunit of 118 amino acids (FSHβ), which confers its specific biologic action and is responsible for interaction with the FSH receptor. The sugar part of the hormone is composed of fucose, galactose, mannose, galactosamine, glucosamine, and sialic acid, the latter being critical for its biologic half-life. The half-life of FSH is 3–4 hours. FSH regulates the development, growth, pubertal maturation, and reproductive processes of the human body. |
