A- -butyric acid

An industrial example of acidolysis is the reaction of poly(vinyl acetate) with butyric acid to form poly(vinyl butyrate). Often a butyric acid—methanol... [Pg.383]

Interestingly methotrexate 24, a well-known dihydrofolate reductase inhibitor that is clinically used for a number of indications such as leukemia and severe psoriasis, has recently been shown to interfere with HD AC activity [80]. Structurally, it may be regarded as a butyric acid derivative. [Pg.14]

E. S. Guthrie (1917) says as a summary to Jiis experiments with butter that chemical changes in the butter were very slight when biological agents were held in check, that enzymic development produced no rancidity and that exposure of butter fat to high temperatures, light and air, did not cause rancidity. In this work rancidity in butter was considered as a butyric acid flavor. [Pg.383]

A A Butyric acid, whose empirical formula is C2H4O, is the acid responsible for the odor of rancid butter. [Pg.395]

The development of processes for the production of butyric acid by fermentation has centered on two species of Clostridium, C. butyricum and C. tyrobutyricum. Experiments employing C. tyrobutyricum seem the most promising primarily because strains of this bacterium are highly selective for butyric acid over acetic acid, both of which are produced simultaneously during fermentation of carbohydrates. For example, in batch culture, C. butyricum produces a butyric acid to acetic acid weight ratio (B/A) of 2.0-2.5, whereas the B/A for C. tyrobutyricum is 4.0-6.0. Thus, compared to C. butyricum,... [Pg.146]
