butyric acid is a carboxylic acid also classified as a fatty acid. it exists in two isomeric forms as shown previously, but this entry focuses on n-butyric acid or butanoic acid. it is a colorless, viscous, rancid-smelling liquid that is present as esters in animal fats and plant oils. butyric acid exists as a glyceride in butter, with a concentration of about 4%; dairy and egg products are a primary source of butyric acid. when butter or other food products go rancid, free butyric acid is liberated by hydrolysis, producing the rancid smell. it also occurs in animal fat and plant oils.
