Follicle stimulating hormone is a hormone synthesized and secreted by the pituitary gland, belongs to the glycosylation of the protein hormones, first discovered its irritating effect on women follicle maturation and named. Later studies showed that the follicle-stimulating hormone in both men and women are one of the very important hormone in the body, regulates the development, growth, puberty, sexual maturity, and reproductive-related a series of physiological processes. Follicle-stimulating hormone and luteinizing hormone in the reproduction-related cooperative plays a key role in the physiological processes.
FSH is a glycoprotein, active form of glycosylation of Heterologous Dimer, formed by α and two β polypeptides. Luteinizing hormone, thyroid hormone, and glycoprotein hormones such as human chorionic gonadotropin with follicle stimulating hormone-similar structures. They share the same alpha subunit (contains 92 amino acid residues), while the β subunits vary, with the hormone. Follicle-stimulating hormone β subunits contain 118 amino acid residues and is responsible for interaction with follicle stimulating hormone receptor. FSH glycosylation involves the algae on the surface of glucose, Galactose, mannose, galactosamine, glucosamine, and Silicon aluminate. Among them, aluminum silicate and closely related to the biological half-life of follicle-stimulating hormone. Follicle-stimulating hormone half-life of 3-4 hours. Follicle-stimulating hormone's molecular weight is about 30000Da.
