Glycoprotein hormones are made up of 2 non-co valently linked subunits a and B (1, 7). The a subunit is a 92 amino-acid peptide, produced by a single gene. It is virtually identical within the same species for the 4 pituitary glycoprotein hormones (8). The B subunits, produced by different genes, differ ac cording to the hormones (9, 10). FSH is a dimeric glycoprotein with an α protein subunit common to LH and thyroid stimulating hormone from the pituitary gland and human chorionic gonadotrophin (HCG) from the placenta. The α subunit is bound non-covalently to a β subunit unique to each hormone which together confer biological :// Pituitary–testicular axis function, biological to immunological ratio and charge isoform distribution of pituitary LH in male rats with experimental diabetes General and Comparative Endocrinology, Vol. , No. 3 Glycoprotein Hormones: Some Aspects of Studies of Secondary and Tertiary Structure.

The understanding of the molecular basis of gonadotropin hormone action requires a knowledge of the structural properties of the hormones Amino acid sequence analyses (see reviews in Wallis, ; Pierce et al., ; Dayhoff, ) have shown that gonadotropins and thyrotropin (TSH) share a common subunit of 89–96 amino acid residues with five disulfide bonds, designated :// This book addresses the interrelationship of pituitary and ovarian hormones in controlling ovulation and the preparation of the intrauterine environment for implantation.

Since , GPHs are known to consist of two different glycoprotein subunits, called α and β, that are non-covalently associated (9–12). This heterodimeric structure has been known for a long time to be mandatory for their respective biological Biochemical Aspects of Hormones 1. from anterior pituitary •Glycoprotein •Two subunits α and β •α subunit is identical to the α subunit of LH, FSH, and hCG-α •β subunit is specific for TSH •TSH receptor: G protein-coupled, 7- transmembrane segment receptor that activates adenylyl cyclase through Gs •Enhances iodide All of the pituitary hormones are peptide or protein hormones based on their chemical structure. Several hormones stimulate distant endocrine glands to increase production of their own hormones. These stimulatory hormones anterior pituitary hormones are often called trophic or tropic the importance of these hormones in regulation of growth, development, lactation reproduction
