C Alkaline phosphatase

(Ref: 23rd edition Ganong's Page-301)

I. Biochemical markers of bone formation are

a. serum alkaline phosphatase,

b. osteocalcin, and

c. the carboxy-terminal extension peptide of pro-collagen 1.

II. Osteocalcin is secreted solely by osteoblasts and thought to play a role in the body's metabolic regulation and is pro-osteoblastic, or bone-building, by nature.It is also implicated in bone mineralization and calcium ion homeostasis.

III. Procollagen 1 Carboxyterminal Peptide (P1CP) is the precursor of collagen, synthesized in osteoblasts and fibroblasts and subsequently converted to form collagen by procollagen peptidase.
