Metabolite Identification
Common Name1,1-Dimethoxyheptane
Description1,1-Dimethoxyheptane 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. 1,1-Dimethoxyheptane is a fruity, green, and orange tasting compound. 1,1-Dimethoxyheptane has been detected, but not quantified in, blackberries (Rubus) and evergreen blackberries (Rubus laciniatus). This could make 1,1-dimethoxyheptane a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 1,1-Dimethoxyheptane.
