Fatty acids (FAs) constitute an essential lipid class in all living systems, serving pivotal biological roles in various physiological functions and during inflammation, affecting immune response and apoptosis. Moreover, FAs are building blocks of many complex lipid structures where they are coupled via an ester, ether, or amide linkage to structural backbones including glycerol, sphingosine and carbohydrates. The general FA structure consists of a carboxylic acid group and a hydrocarbon chain.
