Osteocalcin (OST) which is also called bone Gla protein (B.G.P) is a 49 amino-acids peptide which contains three residues of gamma carboxyl glutamic acids and is 5800 Da in molecular weight. It is synthesised in the bone by the osteoblasts where after its production it is partly incorporated in the bone matrix, the rest of it is found to be circulating in blood.
