1. pertaining to hydrophobia (rabies).
2. repelling water; insoluble in water; not readily absorbing water.

hydrophobic interaction
interaction of nonpolar (un-ionizable) hydrocarbon molecules forced together because of stronger water-water interaction.
hydrophobic signal peptides
15 to 30 amino acids located at or near the N-terminus of a protein that always includes a hydrophobic core of at least eight nonpolar amino acids, found in proteins that are synthesized on membrane bound ribosomes and destined for export from the cell.
