NCIt synonyms : Cross-Linked C-Terminal Telopeptide of Type I Collagen; C-Terminal Telopeptide Type 1 Collagen; C-Telopeptide; C-Terminal Telopeptide Type I Collagen; CTXI; CTX-I; Collagen Type 1 Cross-linked C-Telopeptide;
NCIt definition : This polypeptide is comprised of the carboxy-terminal portions of fibrillar collagen,
which are joined through trivalent crosslinks and released during the degradation
of mature type I collagen by cathepsin K. Serum concentrations of these peptides can
be correlated with the rate of bone metabolism.;
NCIt note : Triple helical collagen is constructed from more than one gene product; thus, C-telopeptides
arise from heterogeneous sources.;
