Calcitonin is cyclic peptide hormone that stimulates bone formation by osteoblasts and inhibits bone resorption. Calcitonin is a hypocalcemic hormone produced by the parafollicular C cells of the thyroid or by the ultimobranchial bodies of non-mammalian vertebrates. It decreases blood calcium and phosphate due to inhibition of resorption by osteoblasts and osteocytes. Salmon calcitonin is more potent than mammalian forms. Calcitonin, salmon [Des-Cys1] is an analog in which the N-terminal Cys has been replaced with Ser.
