Metabolite Identification
Common NameEthyl propionate
DescriptionEthyl propanoate, also known as fema 2456, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom, forming an ester group. Ethyl propanoate exists as a solid. It is very hydrophobic, practically insoluble in water, and a relatively neutral molecule. Ethyl propanoate exists in all eukaryotes, ranging from yeast to humans. Ethyl propanoate has been found to be associated with several known diseases as autism, irritable bowel syndrome, ulcerative colitis, and nonalcoholic fatty liver disease; also ethyl propanoate has been linked to the inborn metabolic disorders including celiac disease. As a volatile organic compound, ethyl propionate has been identified as a fecal biomarker of Clostridium difficile infection (PMID:30986230 ).
