Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor.
Body Odor and Disease. In mammals, body odor can also be used as a symptom of disease. One's body odor is completely unique to themselves, similar to a fingerprint, and can change due to sexual life, genetics, age and diet. Body odor, however, can be used as an indication for disease.
The molecule can be described as a condensation of two molecules of butyric acid with elimination of one water molecule (hence its name). Butyric anhydride is a clear colorless liquid that smells strongly of butyric acid, which is formed by its reaction to moisture in the air.
Body odor encompasses axillary (underarm) odor and foot odor. [1] It is caused by a combination of sweat gland secretions and normal skin microflora. [1] In addition, androstane steroids and the ABCC11 transporter are essential for most axillary odor. [1] [2] Body odor is a complex phenomenon, with numerous compounds and catalysts involved in ...
These bacteria produce carbon dioxide and a number of compounds that account for the unique odor: pungent (propionic acid), rotten-egg (hydrogen sulfide), rancid-butter (butyric acid), and vinegary (acetic acid). [8] Due to these gases, a thousand cans of surströmming exploded over a period of six hours during a fire at a Swedish warehouse in ...
Butyraldehyde undergoes reactions typical of alkyl aldehydes, and these define many of the uses of this compound.Important reactions include hydrogenation to the alcohol, oxidation to the acid, and base-catalyzed condensation.
β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
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 ...
