Meaning " water fearing". Denoting the property of attracting or associating with water molecules, possessed by polar radicals or ions, as opposed to hydrophobic (2). ... has both a hydrophilic region and hydrophobic region: Term. A phospholipid is unique in that it has a hydrophilic region called the head, and a hydrophobic region known as the tail. Attracted to water; used in reference to molecules, or portions of molecules (e.g., amino, carboxyl, and hydroxyl groups), that have an affinity for water. Draw a simplified diagram of the structure of the phospholipid, including a phosphate-glycerol head and two fatty acid tails. hydrophobic: [ hi″dro-fo´bik ] 1. repelling water; insoluble in water; not readily absorbing water. CallUrl('www>macroevolution>nethtml',0), ~TildeLink() The property of a substance that has a tendency to attract water.hydrophobic The property of a substance that has a tendency to repel water.hydroponics A system of growing plants in a liquid nutrient solution without soil. “Water-loving”—generally, ions and molecules that contain polar covalent bonds will dissolve in water and are said to be hydrophilic. It refers to having a strong affinity for water. Meaning of hydrophilic . Something that is hydrophilic is soluble in water and dissolves into water very easily. I thought I’d do the opposite, using as many pictures as possible to explain hydrophilic, hydrophobic, ultrahydrophobic, ultrahydrophilic, and amphipathic. ; A hydrophilic colloid, or hydrocolloid, is defined as a colloid system in which the colloid particles are hydrophilic polymers dispersed in water. Having an affinity for water; readily absorbing or dissolving in water. (Oxford Biology Course Companion page 26). Something that is hydrophilic is soluble in water and dissolves into water very easily. Learn / Biology / Hydrophilic Substances Hydrophilic Substances A hydrophilic particle or segment of an atom is one whose associations with water and other polar substances are more thermodynamically stable and strong than their cooperation with oil or other hydrophobic solvents.

Medical Definition of hydrophilic (Entry 1 of 2) : of, relating to, or having a strong affinity for water hydrophilic colloids swell in water and are relatively stable soft contact lenses are made of hydrophilic … The nonpolar head is not attracted to water and is said to be hydrophobic. Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. CallUrl('www>biology>arizona>eduhtml',0), That model shows that the phospholipids are in a shape like a head and a tail.
