Propionic acid (from the Greek words protos, meaning first, and pion, meaning fat; also known as propanoic acid) is a naturally occurring carboxylic acid with chemical formula C H 3 CH 2 C O OH.acteria of the genus Propionibacterium produce propionic acid as the end-product of their anaerobic metabolism. This class of bacteria is commonly found in the stomachs of ruminants and the sweat glands of humans, and their activity is partially responsible for the odor of both Swiss cheese and sweat.
Each person's unique body odor can be influenced by diet, gender, health, and medication. Propionic acid (propanoic acid) is commonly found in sweat - propionibacteria break amino acids down into propionic acid. Propionibacteria live in the ducts of the sebaceous glands of adult and adolescent humans.
