Butyric Acid is an organic compound that is responsible for the smell of butter that has gone sour. Butyric Acid is a substance that was isolated from butter in 1869. It is also known as butanoic acid or butyrate. Butyric acid, a four-carbon fatty acid, is formed in the human colon by bacterial fermentation of carbohydrates (including dietary fiber), and putatively suppresses colorectal cancer (CRC). It has diverse and apparently paradoxical effects on cellular proliferation, apoptosis and differentiation that may be either pro-neoplastic or anti-neoplastic, depending upon factors such as the level of exposure, availability of other metabolic substrate and the intracellular milieu. Butyric acid is a medium-strong acid that reacts with bases and strong oxidants, and attacks many metals. It is a carboxylic acid, as defined by the COOH group. Butyric acid is prepared on a large scale by the fermentation of starch or sugar. It is found most commonly in butter, but can also be present in some fruits. Butyric acid is also produced synthetically, through fermentation of various carbohydrates, to be used as a flavoring agent in various food products. It is also used for the production of plastics, plasticizers, surfactants and textile auxiliaries. Butyric acid and its derivatives are also being seriously considered around the world as potential anticancer agents.
