Effect of surfactants on the thermal, conformational and rheological properties of collagen

Viscoelastic adlayers of collagen and lysozyme studied using quartz crystal microbalance with dissipation monitoring

“…4). However, because the conformational difference is small (as previously reported [22]), it is at best attributable to a different helix pitch, with the overall collagen helix conformation maintained. Nevertheless, the rheology related to these two conformations [23] is different, as seen from the D curves in the QCM-D results for each pH (Figs.…”

Directed 2-dimensional organisation of collagen: Role of cross-linking and denaturing agents

“…Surfactants are known to act as denaturants. 16 Since both crosslinking agent like curcumin and denaturants like surfactants are decreasing the surface tension of the protein, there may be two different mechanisms operating to influence the surface activity. Curcumin is likely to alter the hydration network around the protein while denaturants break the water structure.…”

Structural properties of pepsin-solubilized collagen acylated by lauroyl chloride along with succinic anhydride

“…CD experiments of native and acylated collagens were carried out by the method of Fathima and Dhathathreyan with slight modification [22]. Lyophilized acylated collagen and native collagen were dissolved in 0.01 mol/L phosphate saline buffer (PBS, pH 7.4) and 0.01 mol/L acetic acid solution respectively, to obtain the concentrations of 0.1 mg/mL.…”
