Glossary Hydrophobicity

property of repelling water

Hydrophobicity refers to the property of a molecule or surface that repels water. In simpler terms, it means that the substance does not mix with or absorb water, much like how oil behaves when it is in contact with water. This characteristic is crucial in various biological processes, such as the formation of cell membranes, where hydrophobic lipid tails face inward, away from water, creating a barrier that protects the cell.
