The Hydrophobic Effect - Medium

WebThe hydrophilic head is made up of Gycerol and a phosphate group - it is the phosphate group which makes the head hydrophilic. The hydrophobic tail is made up of 2 fatty acid chains, one of which usually contains a Cis double bond (C=C). This double bind causes the tail to 'kink' which affects the packing structure and fluidity of the bilayer. WebTherefore, the formation of the hydrophobic bonds is spontaneous. Hydrophilic molecules are molecules that can dissolve in water. That is, the hydrophilic molecules attract water molecules. The hydrophilic character of a molecule can be described as its hydrophilicity.
