Study Notes
Fatty Acids
- Fatty acids are the major component of lipids in some species.
- In some organisms, fatty acids exist as a class of esters called triglycerides.
- The concept of fatty acid was introduced by Michel Eugène Chevreul in 1813.
Definition and Structure
- In biochemistry, a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated.
- Most naturally occurring fatty acids have a range of 4-30 carbon atoms, with a common range of 12-24 carbon atoms.
Classification
- Fatty acids exist in three main classes of esters in some organisms: triglycerides, phospholipids, and cholesterol esters.
- There are two types of fatty acids based on saturation: saturated fatty acids (having no double bonds) and unsaturated fatty acids (having one or more double bonds).
