hydrophobic /hy·dro·pho·bic/ (-fo´bik) 1. pertaining to hydrophobia (rabies). 2. not readily absorbing water, or being adversely affected by water. 3. lacking polar groups and therefore insoluble in water.
hydrophobic, adj refers to the resistance of a substance to combine with water. Hydrophobic substances, such as oil, are composed of nonpolar molecules, which tend to clump together and repel water. hydrophobic 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. |

This treatment transforms the MgO in a heater's cold section from hygroscopic to hydrophobic, so it will not absorb or retain moisture. Key statement: Upon application, the cartier solvent/reactant evaporates, allowing polymerization of the remaining solution constituents to form a non-toxic, hydrophobic, elastomeric polyurethane linked copolymer that provides a long-term barrier against rot, environmental, termite and mold/fungus attack. Specifically, as the surface of hair (cuticle) is hydrophobic while the inside of hair is hydrophilic, SDK has synthesized a thiol-based compound having both hydrophobic and hydrophilic parts. |
