A qualitative term referring to the water-avoiding nature of a species A functional group of a molecule that is not very water-soluble is referred to as a hydrophobe
Means water insoluble and refers to non-polar properties as opposed to polar properties of water Water soluble, or hydrophilic, molecules do not easily mix with hydrophobic molecules or solutions Oil is a hydrophobic substance and mixtures of oily and watery molecules tend to minimize their contact surface Thus the observed separation of oil from water when left standing However, oil can be partially mixed with water when shaking a container vigorously indicating that the separation or mixing of molecules is determined by the energy of molecular interaction The energy to overcome these molecular interactions can be provided by mechanical force (shaking) or high temperature The latter is a well known observation; salts, sugars, and fats normally mix better in hot than cold water, and hot water is better in removing stains form dishes or cloths
abnormally afraid of water lacking affinity for water; tending to repel and not absorb water; tending not to dissolve in or mix with or be wetted by water
"Water hating" Those functional groups or molecules which prefer to be in an environment where there is no water; an oily environment
{s} suffering from hydrophobia (abnormal fear of water); lacking attraction for water
Literally, "water-fearing"; nonpolar compounds that are immiscible with water The side chains of some amino acids are nonpolar, and hence protein sequences rich in these amino acids tend to locate to the interior of the protein in its native state, away from the solvent
`water-hating', typically non-polar molecules or parts of molecules are hydrophobic as they are not attracted to water molecules which are polar Compare hydrophilic
In chemistry, hydrophobicity (from the combining form of water in Attic Greek hydro- and for fear phobos) refers to the physical property of a molecule (known as a hydrophobe) that is repelled from a mass of water
