The word "butyl" is derived from butyric acid, a four-carbon carboxylic acid found in rancid butter. [1] The name "butyric acid" comes from Latin butyrum , butter . Subsequent preferred IUPAC names for alkyl radicals in the series are simply named from the Greek number that indicates the number of carbon atoms in the group: pentyl , hexyl ...
Clostridium butyricum is a strictly anaerobic endospore-forming Gram-positive butyric acid–producing bacillus subsisting by means of fermentation using an intracellularly accumulated amylopectin-like α-polyglucan (granulose) as a substrate. It is uncommonly reported as a human pathogen and is widely used as a probiotic in Japan, Korea, and ...
Some liquids use butyric acid instead of diacetyl and acetyl propionyl, but it could have negative health effects. [241] Concerns exist that the flavors and additives in e-cigarettes might lead to diseases, including the popcorn lung. [55] The cardiovascular effects, including a vast range of flavorings and fragrances, is unknown. [242]
