What is Bone resorption markers are except: and explain in detail?
Osteocalcin Osteocalin is a non-collogenous protein secreted by osteoblasts. It is thought to play a role in mineralization and calcium ion hemostasis. "Thus it is a bone formation marker i.e. osteoblastic marker". A large number of studies have shown that the circulating level of osteocalcin reflects the rate of bone formation (not resorption).
