| N-(p-Aminobenzoyl)glutamic acid Usage And Synthesis |
| Chemical Properties | Light Tan Waxy Solid | | Uses | Marker in folate metabolism studies. | | Uses | Major metabolite of 5-Methyltetrahydrofolic Acid | | Definition | ChEBI: A dipeptide resulting from the formal condensation of the carboxylic acid group of 4-aminobenzoic acid with the amino group of L-glutamic acid. | | Purification Methods | Crystallise the acid from H2O. Also purify it by dissolving 2.7g in H2O (130mL), adding aqueous NaOH to pH 5.5 and adding portionwise a solution of 0.5M CuSO4 to complete precipitation of the Cu salt. This salt is filtered off, suspended in H2O and H2S is bubbled through to precipitate CuS, filter, evaporate and recrystallise the residue from H2O. It has max (H2O) at 273nm.
