10-Formyltetrahydrofolate (BioDeep_00000004199)

描述信息

10-formyltetrahydrofolate, also known as 10-formyl-thf or 10-formyltetrahydropteroylglutamic acid, is a member of the class of compounds known as tetrahydrofolic acids. Tetrahydrofolic acids are heterocyclic compounds based on the 5,6,7,8-tetrahydropteroic acid skeleton conjugated with at least one L-glutamic acid unit. 10-formyltetrahydrofolate is practically insoluble (in water) and a moderately acidic compound (based on its pKa). 10-formyltetrahydrofolate can be found in a number of food items such as agave, black salsify, white cabbage, and lemon, which makes 10-formyltetrahydrofolate a potential biomarker for the consumption of these food products. 10-formyltetrahydrofolate exists in all eukaryotes, ranging from yeast to humans. In humans, 10-formyltetrahydrofolate is involved in several metabolic pathways, some of which include mercaptopurine action pathway, methionine metabolism, purine metabolism, and folate malabsorption, hereditary. 10-formyltetrahydrofolate is also involved in several metabolic disorders, some of which include myoadenylate deaminase deficiency, adenine phosphoribosyltransferase deficiency (APRT), molybdenum cofactor deficiency, and cystathionine beta-synthase deficiency. 10-Formyltetrahydrofolate (10-CHO-THF) is a form of tetrahydrofolate that acts as a donor of formyl groups in anabolism. In these reactions 10-CHO-THF is used as a substrate in formyltransferase reactions. This is important in purine biosynthesis, where 10-CHO-THF is a substrate for phosphoribosylaminoimidazolecarboxamide formyltransferase, as well as in the formylation of the methionyl initiator tRNA (fMet-tRNA), when 10-CHO-THF is a substrate for methionyl-tRNA formyltransferase .
