On the mechanism of SDS-induced protein denaturation

WebDetergent-based cell lysis. Both denaturing and non-denaturing cell lysis reagents may be used for protein extraction procedures. Denaturing detergents such as SDS bind to both membrane (hydrophobic) and … The origin of the hydrophobic effect is not fully understood. Some argue that the hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the nonpolar solute. A hydrocarbon chain or a similar nonpolar region of a large molecule is incapable of forming hydrogen bonds with water. Introduction of s…
