| 摘要 |
<p>Degradation of body proteins such as bone collagen is studied by detecting in body fluids isomerized peptide fragments of said proteins in which peptide bonding to the α-carboxylic acid group of aspartic acid or asparagine has become isomerized to an amide bond to the side chain carboxylic acid group of aspartic acid. Antibodies specific for the isomerized peptide sequences are used in assays.</p> |
