DescriptionPropionic acid, also known as acide propanoique or propionate, belongs to the class of organic compounds known as carboxylic acids. Carboxylic acids are compounds containing a carboxylic acid group with the formula -C(=O)OH. Propionic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Propionic acid exists in all living species, ranging from bacteria to humans. Propionic acid is a potentially toxic compound.

Enzymes

General function:
Involved in acetate-CoA ligase activity
Specific function:
Catalyzes the production of acetyl-CoA. Provides the acetyl-CoA source for histone acetylation in the nucleus. "Aerobic" isozyme of acetyl-coenzyme A synthetase, which supports growth on nonfermentable carbon sources such as glycerol and ethanol. May be required for assimilation of ethanol and acetate
