(C) The subregions of a glycerophospholipid molecule; phosphatidylcholine is shown as an example. The hydrophilic head is composed of a choline structure (blue) and a phosphate (orange).

One end of the molecule is hydrophilic and the other ... The first clues to lipid bilayer structure came from results with red blood cell membranes. The ultimate discovery that the plasma membrane ...

Consider the hydrolysis of this triglyceride ... Each molecule consists of a long non-polar covalent hydrocarbon ‘tail’ and a polar, ionic ‘head’ where the charge is. This structure ...
