Minimizing the number of hydrophobic side-chains exposed to water (the hydrophobic effect) is an important driving force behind the folding process.

Web- Hydrophobic effect - Hydrogen bonds - Electrostatic interactions - Conformational entropy When proteins are unfolded, they are unstable so have a lot of energy. When they are folded into coils, they are stable so they exist as a minimum energy amount. How can protein folding be monitored? By fluorescence: - Using Trp as a probe.

WebThe role of the environment in amyloid formation based on the fuzzy oil drop model (FOD) is discussed here. This model assumes that the hydrophobicity distribution within a globular protein is consistent with a 3D Gaussian (3DG) distribution. Such a distribution is interpreted as the idealized effect of the presence of a polar solvent—water.
