Chemical Information
FooDB Name2,4-Pentanedione
Description2,4-Pentanedione, also known as ACAC or 2,4-dioxopentane, belongs to the class of organic compounds known as beta-diketones. These are organic compounds containing two keto groups separated by a single carbon atom. Thus, 2,4-pentanedione is considered to be an oxygenated hydrocarbon. 2,4-Pentanedione has been detected, but not quantified in, a few different foods, such as blackberries (Rubus), evergreen blackberries (Rubus laciniatus), and papayas (Carica papaya). This could make 2,4-pentanedione a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 2,4-Pentanedione.
