• Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.
• Fatty acids are a major component of the lipids in some species such as microalgae but in some other organisms are not found in their standalone form, but instead exist as three main classes of esters: triglycerides, phospholipids, and cholesteryl esters.
• In any of these forms, fatty acids are both important dietary sources of fuel for animals and important structural components for cells.
