h: To compute the Eisenberg (1984) hydrophobicity index
Description
Hydrophobicity scales are values that define relative hydrophobicity of amino acid residues. These scales are commonly used to predict the transmembrane alpha-helices of membrane proteins. When consecutively measuring amino acids of a protein, changes in value indicate attraction of specific protein regions towards the hydrophobic region inside lipid bilayer. This index is calculated using the scale proposed by Eisenberg in 1984.
