A hydrophilic molecule or portion of a molecule is one whose interactions with water and other polar substances are more thermodynamically favorable than their interactions with oil or other hydrophobic solvents.nother example is soap, which has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively.
All of the answers are correct. amphipathic means has both hydrophilic and hydrophobic chains and detergents have this property plus they form micelles which have a hydrophillic outer layer and a hydrophobic core needed to dissolve oily substances. The plasma membrane is a lipid bilayer made out of a double layer of phospholipids. The phospholipids incorporate a phosphate head that's hydrophilic (water-loving) and a pair of fatty acid tails that are hydrophobic (water hating). The heads face outwards and the tails face inwards making up the membrane.
