Phospholipids. Phospholipids make up an important class of lipids for the construction of cell membranes.

Defining Characteristics of Phospholipids. Phospholipids are major components of the plasma membrane, the outermost layer of animal cells.

Unlike triglycerides, which have three fatty acids, phospholipids have two fatty acids that help form a diacylglycerol.
