Cell Biology/Membranes/Hydrophobicity. Hydrophobicity literally means fear of water. The opposite of this is hydrophilicity which means love of water. These two terms denote the properties of molecules or parts of molecules to bond with water (hydrophilicity) or reject water (hydrophobicity). This effect is seen when one puts a drop of oil on water.
Hydropathy is a term that refers to the spectrum of amino acid side chains in the hydrophilicity-hydrophobicity scale. It was originally coined by Kyte and Doolittle(1) in an article describing an algorithm that identifies helical transmembrane spans and that came to be widely used.n example of a hydropathy prediction is shown in Figure 1. In the cases of bacteriorhodopsin, cytochrome oxidase, and bacterial photosynthetic reaction center, this simple analysis correctly identified the approximate positions of all the transmembrane helices, with no false positives.
