Butyric Acid

Butyric acid, also known under the systematic name butanoic acid, is a straight-chain alkyl fatty acid with the chemical formula CH3CH2CH2COOH. It is an oily, colorless liquid with an unpleasant odor. Isobutyric acid is an isomer. Salts and esters of butyric acid are known as butyrates or butanoates. The acid itself does not occur widely in nature, but its esters are widespread. It is a common industrial chemical and an important component in the mammalian gut.
