产品说明：

In humans, the total pool of urinary Pyd is approximately 45% free while the remaining fraction is bound to oligopeptides ranging from small linear peptides to very large cross-linked structures in excess of 10,000 Da. The proportion of free to total cross-links appears to be constant in healthy individuals and those with metabolic bone diseases or arthritis conditions, thus providing the rationale for measuring free Pyd.
