Common NamePear ester
DescriptionEthyl 2Z,4E-decadienoic acid, also known as ethyl (2E,4Z)-decadienoate or ethyl 2-trans-4-cis-decadienoate, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Ethyl 2Z,4E-decadienoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Ethyl 2Z,4E-decadienoic acid is a sweet, apple, and creamy tasting compound. Outside of the human body, Ethyl 2Z,4E-decadienoic acid has been detected, but not quantified in, several different foods, such as asian pears, fruits, pears, and pomes. This could make ethyl 2Z,4E-decadienoic acid a potential biomarker for the consumption of these foods. A fatty acid ethyl ester resulting from the formal condensation of the carboxy group of (2E,4E)-deca-2,4-dienoic acid with the hydroxy group of ethanol. Pear ester is found in Strychnos madagascariensis , Thrixspermum arachnites and Vitis spp. . Pear ester was first documented in 2007 (PMID: 17992562). Ethyl 2Z,4E-decadienoic acid is a potentially toxic compound (PMID: 18189264) (PMID: 18284724) (PMID: 21882697) (PMID: 22507015).
