Common Name | Pteroyltriglutamic acid |

Description | Pteroyltriglutamic acid is a crystalline conjugate of folic acid containing three molecules of glutamic acid instead of one and having the general properties of a polypeptide. As a measure of enterocyte function, the deconjugation of Pteroylpolyglutamic acid (pteroyl-L-glutamyl-gamma-L-glutamyl-gamma-L-glutamic acid) to folic acid and subsequent active absorption was measured in 19 patients with progressive systemic sclerosis and compared with 14 controls. The absorption step of folic acid was identical in the two groups, while deconjugation of pteroyl-L-glutamyl-gamma-L-glutamyl-gamma-L-glutamic acid was significantly decreased in the patients with progressive systemic sclerosis. This observation suggests a primary epithelial defect of the small intestine in patients with progressive systemic sclerosis. (PMID 3583071 ). Glutamyl hydrolase cleaves the poly-g-glutamate chain folate and antifolate poly-g-glutamates. Its cellular location is lysosomal with large amts. Of the enzyme constitutively secreted. The highest levels of glutamyl hydrolase mRNA in humans is found in the liver and kidney (PMID: 10598552 ). |
