WebMar 25, 1975 · The major folate metabolites found in L. casei preloaded with high levels of [3H]PteGlu (0.5 mum) were 10-formyl-H4PteGlu2 and 10-formyl-PteGlu. Both compounds were released, the monoglutamate more rapidly. Pteroyltriglutamate formation appeared to be a rate-limiting step in intracellular metabolism. WebIt is converted into 5,10-methylenetetrahydrofolate by serine hydroxymethyltransferase . Bacterial synthesis [ edit] Many bacteria use dihydropteroate synthetase to produce dihydropteroate, a molecule without function in humans. This makes it a useful target for sulfonamide antibiotics, which compete with the PABA precursor. bowling results today

Blue arrows are pathways specific to mammals. The biological activity of folate in the body depends upon dihydrofolate reductase action in the liver which converts folate into tetrahydrofolate (THF). This action is rate-limiting in humans leading to elevated blood concentrations of unmetabolized folic acid when consumption from dietary supplements and fortified foods nears or exceeds the U.S. Tolerable Upper Intake Level of 1,00… gum that lasts the longest
