| Common Name | Capsiate |

| Description | Capsiate, also known as dihydrocapsiate or capsiic acid, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. A carboxylic ester obtained by formal condensation of the carboxy group of (6E)-8-methylnon-6-enoic acid with the benzylic hydroxy group of vanillyl alcohol. Capsiate is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Capsiate has been detected, but not quantified in, several different foods, such as yellow bell peppers, red bell peppers, italian sweet red peppers, orange bell peppers, and green bell peppers. This could make capsiate a potential biomarker for the consumption of these foods. Capsiate is found in Apis cerana and Capsicum annuum . Capsiate was first documented in 2003 (PMID: 12726827). A non-pungent analogue of capsaicin with a similar biological profile (PMID: 12959953) (PMID: 16636441) (PMID: 17264228) (PMID: 17971242). |
