1. a lipid molecule containing phosphorus, typically composed of a glycerol backbone with fatty acids and a phosphate group; a major structural component of cell membranes.
Usage: technical/scientific term; commonly used in biochemistry and cell biology

Examples

• Phospholipids form the lipid bilayer that makes up the cell membrane.
• The hydrophobic tails and hydrophilic heads of phospholipids allow them to self-assemble in water.
• Scientists study phospholipids to understand how cells regulate their membrane properties.
• Phospholipids are essential for the proper functioning of all living cells.
• The brain contains high concentrations of phospholipids, particularly in myelin sheaths.
• Dietary sources of phospholipids include eggs, fish, and soybeans.
