Phospholipids. Phospholipids make up an important class of lipids for the construction of cell membranes. The phospholipids are not true fats because they have one of the fatty acids replaced by a phosphate group.This sketch of a phospholipid molecule shows two fatty acids and a phosphate group attached to a glycerol backbone.hospholipids. Phospholipids make up an important class of lipids for the construction of cell membranes. The phospholipids are not true fats because they have one of the fatty acids replaced by a phosphate group.
 Phospholipids are important because they are amphipathic, in other  words the two ends of the molecule are different; the fatty acids  form a hydrophobic region, whereas the phosphate is hydrophilic.o, they are called phospholipids because they are made of lipids  and phosphate group. Most phospholipids contain a diglyceride, a  phosphate group, and a simple organic mo â¦ lecule such as choline. Johnellishartford. 14,297 Contributions.
