The hydrophobic-polar protein folding model is a highly simplified model for examining protein folds in space. First proposed by Ken Dill in 1985, it is...

The more positive the value, the more hydrophobic are the amino acids located in that region of the protein. These scales are commonly used to predict...

3D structure is the distribution of polar and non-polar side chains. Folding is driven by the burial of hydrophobic side chains into the interior of the...
