Metabolite Identification
Common Name2,6,6-Trimethyl-1-cyclohexen-1-acetaldehyde
Description2,6,6-Trimethyl-1-cyclohexen-1-acetaldehyde belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. 2,6,6-Trimethyl-1-cyclohexen-1-acetaldehyde is a beef, camphor, and cooling tasting compound. 2,6,6-Trimethyl-1-cyclohexen-1-acetaldehyde has been detected, but not quantified in, cauliflowers (Brassica oleracea var. botrytis). This could make 2,6,6-trimethyl-1-cyclohexen-1-acetaldehyde a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2,6,6-Trimethyl-1-cyclohexen-1-acetaldehyde.
