Lipids and Their Types

Simple lipids are esters of fatty acids with various alcohols, classified mainly as neutral fats (triacylglycerols), waxes, and cholesterol esters.

Compound lipids are esters of fatty acids with certain other compounds in addition to glycerol and fatty acids; an example is phospholipids.

Phospholipids primarily function to form cell membranes and enable cell signaling.
