| Common Name | 2-Hydroxyestradiol-3-methyl ether |

| Description | 2-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 is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Methylcitric acid exists in all living organisms, ranging from bacteria to humans. Outside of the human body, 2-Methylcitric acid has been detected, but not quantified in, milk (cow). This could make 2-methylcitric acid a potential biomarker for the consumption of these foods. 2-Methylcitric acid is a potentially toxic compound. 2-Hydroxyestradiol-3-methyl ether was first documented in 1981 (PMID: 7313494). 2-Methylcitric acid, with regard to humans, has been found to be associated with the diseases such as iron deficiency; 2-methylcitric acid has also been linked to several inborn metabolic disorders including biotinidase deficiency, isovaleric acidemia, vitamin B12 deficiency, and propionic acidemia (PMID: 8345822) (PMID: 12113988). |
