骨钙素(γ-羟基谷氨酸—蛋白,BGP)是由成骨细胞合成的一种非胶原性蛋白,其生物学功能还不清楚。BGP主要存在于骨基质中,血清中的BGP浓度仅为若干纤克分子。血清骨钙素(sBGP)同骨中骨钙素结构相同,为新合成蛋白质的一部
Osteocalcin (γ-hydroxyglutamate-protein, BGP) is a non-collagen protein synthesized by osteoblasts and its biological function is not clear. BGP is found mainly in the bone matrix with only a few fibrils of BGP in serum. Serum osteocalcin (sBGP) is identical in structure to osteocalcin in bone and is a newly synthesized protein
