Butyric acid is a typical carboxylic acid that reacts with bases and affects many metals. [12] It is found in animal fat and plant oils , bovine milk , breast milk , butter , parmesan cheese , body odor , vomit and as a product of anaerobic fermentation (including in the colon ).
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 ...
These smaller molecules smell, and give body odor its characteristic aroma. [10] Propionic acid (propanoic acid) is present in many sweat samples. This acid is a breakdown product of some amino acids by propionibacteria, which thrive in the ducts of adolescent and adult sebaceous glands.

Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
This odor is caused by the buildup of a compound called isovaleric acid in affected individuals. [5] In about half of cases, the signs and symptoms of this disorder become apparent within a few days after birth and include poor feeding, vomiting, seizures, and lack of energy that can progress to coma. These medical problems are typically severe ...
Butyraldehyde is produced almost exclusively by the hydroformylation of propylene: . CH 3 CH=CH 2 + H 2 + CO → CH 3 CH 2 CH 2 CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl but rhodium complexes are more common.
3-Mercapto-3-methylbutan-1-ol, also known as MMB, is a common odorant found in food and cat urine. The aromas ascribed to MMB include catty, [3] roasty, broth-like, meaty, and savory, [4] or similar to cooked leeks. [5] MMB is an organosulfur compound with the formula C 5 H 12 OS.
