Metabolite Identification
Common Name2-Methylcitric acid
Description2-Methylcitric acid, also known as 2-methylcitrate, belongs to the class of organic compounds known as tricarboxylic acids and derivatives. These are carboxylic acids containing exactly three carboxyl groups. 2-Methylcitric acid exists in all living organisms, ranging from bacteria to humans. 2-Methylcitric acid has been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), domestic pigs (Sus scrofa domestica), and milk (cow). This could make 2-methylcitric acid a potential biomarker for the consumption of these foods. 2-Methylcitric acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. 2-Methylcitric acid, with regard to humans, has been found to be associated with the diseases such as crohn's disease; 2-methylcitric acid has also been linked to several inborn metabolic disorders including propionic acidemia, isovaleric acidemia, vitamin B12 deficiency, and biotinidase deficiency. Based on a literature review a significant number of articles have been published on 2-Methylcitric acid.
