| Common Name | Formiminoglutamic acid |

| Description | Formiminoglutamic acid, also known as N-formimino-L-glutamate or formimino-glu, belongs to the class of organic compounds known as glutamic acid and derivatives. Glutamic acid and derivatives are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Formiminoglutamic acid is a very strong basic compound (based on its pKa). Formiminoglutamic acid exists in all living organisms, ranging from bacteria to humans. Within humans, formiminoglutamic acid participates in a number of enzymatic reactions. In particular, formiminoglutamic acid can be biosynthesized from 4-imidazolone-5-propionic acid through its interaction with the enzyme probable imidazolonepropionase. In addition, tetrahydrofolic acid and formiminoglutamic acid can be converted into 5-formiminotetrahydrofolic acid and L-glutamic acid through the action of the enzyme formimidoyltransferase-cyclodeaminase. Formiminoglutamic acid (FIGLU) is an intermediate in the catabolism of L-histidine to L-glutamic acid and marker for intracellular levels of folate. In humans, formiminoglutamic acid is involved in histidine metabolism. It is elevated with folate trapping, where it is accompanied by decreased methylmalonic acid, increased folate and a decrease in homocysteine. Formiminoglutamic acid is found in Daphnia pulex. Formiminoglutamic acid was first documented in 1975 (PMID: 235753). The FIGLU test is used to identify deficiencies of vitamin B12 or folate and is also found in liver disease (PMID: 500809) (PMID: 12815595). |
