Effect of beta-aminopropionitrile on bone mechanical properties. 1977

D M Spengler, and D J Baylink, and J B Rosenquist

In vivo beta-aminopropionitrile treatment caused significant changes in the mechanical properties of rat femora. In femora treated with beta-aminopropinitrile as compared with controls, there was a 44 per cent decrease in bone stiffness and a 47 per cent increase in bone deformation to failure. Bone ash was decreased 5 per cent in the treated group. It is likely that the decrease in bone ash was secondary to impaired intermolecular bone-collagen cross-linking, which is a well established consequence of treatment with beta-aminopropionitrile. Thus, beta-aminopropionitrile influences bone mechanical properties directly by impairing collagen cross-linking and indirectly by altering bone-matrix mineralization.

D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
