Thyroid-stimulating hormone (TSH) is a glycoprotein composed of two noncovalently linked subunits, α and β. The structure of TSH from a variety of species has been well characterized, including the amino acid sequence and carbohydrate composition (Pierce and Parsons, 1981). The α-subunit of bovine TSH has a molecular weight of 13,600, of which 10,800 is composed of a protein core of 96 amino acids and 2,800 (21%) represents two oligosaccharide units linked to asparagine residues. Bovine TSH-β has a molecular weight of 14,700, of which 13,100 is comprised of a protein core of 113 amino acids and 1,600 (12%) represents one asparagine-linked oligosaccharide unit.
