| Common Name | Methylglutamic acid |

| Description | Methylglutamic acid, also known as methylglutamate, is a member of the class of compounds known as methyl-branched fatty acids. Methyl-branched fatty acids are fatty acids with an acyl chain that has a methyl branch. Usually, they are saturated and contain only one or more methyl group. However, branches other than methyl may be present. Methylglutamic acid is soluble (in water) and a weakly acidic compound (based on its pKa). Methylglutamic acid can be found in tamarind, which makes methylglutamic acid a potential biomarker for the consumption of this food product. N-Methyl-L-glutamic acid (methylglutamate) is a chemical derivative of glutamic acid in which a methyl group has been added to the amino group. It is an intermediate in methane metabolism. Biosynthetically, it is produced from methylamine and glutamic acid by the enzyme methylamine-glutamate N-methyltransferase. It can also be demethylated by methylglutamate dehydrogenase to regenerate glutamic acid. |
