|Abstract:||There is a confusion in the application of circular dichroism (CD) spectroscopy in analyzing collagen's structure for the overlapping of the spectral shapes and positions of the collagen triple helix and poly(proline-II)-like structure. The unique repetitive sequence of the collagen triple helix is susceptible to misalignment during the spontaneous assembly. Such misaligned structures are usually difficult to be characterized by CD or NMR spectroscopy. Here, RP-HPLC was developed as a conformational characterization technique for synthetic collagen-like peptides based on the different hydrophobicities exhibited by the triple-helical and unassembled peptides. RP-HPLC was also used to study thermal transitions and to measure melting point temperatures (Tm) of the collagen-like peptides. © 2007 Elsevier B.V. All rights reserved.|
