Serum osteocalcin concentrations in infancy: Lower values in those fed cow milk formula versus breast feeding

Osteocalcin is a recentiy discovered vitamin K-dependent calcium-binding Protein that is synthesized by osteoblasts. It has been measured previously in sera, and is elevated in conditions associated with rapid bone turnover, including hyperparathyroidism, renal osteodystrophy, and bone metastases. Out study was designed to test the thesis that serum osteocalcin concentrations would be elevated in infancy and not be affected by dietary intake, race, or
