Metabolite Identification
Common Name6,6-Dimethoxy-2,5,5-trimethyl-2-hexene
Description6,6-Dimethoxy-2,5,5-trimethyl-2-hexene belongs to the class of organic compounds known as acetals. Acetals are compounds having the structure R2C(OR')2 ( R' not Hydrogen) and thus diethers of geminal diols. Originally, the term was confined to derivatives of aldehydes (one R = H), but it now applies equally to derivatives of ketones (neither R = H ). Mixed acetals have different R' groups. 6,6-Dimethoxy-2,5,5-trimethyl-2-hexene is a citrus, fresh, and grapefruit peel tasting compound. Based on a literature review very few articles have been published on 6,6-Dimethoxy-2,5,5-trimethyl-2-hexene.
