Pyridoxal phosphate Usage And Synthesis
Chemical PropertiesLight yellow crystalline
UsesVitamin (enzyme co-factor).
DefinitionThe coenzyme of amino acid metabolism that also is the active group of various decarboxylases and other types of enzymes. It is closely related to pyridoxine.
Purification MethodsPLP has been purified by dissolving 2g in H2O (10-15mL, in a dialysis bag a third full) and dialysing with gentle stirring against 1L of H2O (+ two drops of toluene) for 15hours in a cold room. The dialysate is evaporated to 80-100mL, then lyophilised. Lemon yellow microscopic needles of the monohydrate remain when all the ice crystals have been removed. The purity is checked by paper chromatography (in EtOH or n-PrOH/NH3) and the spot(s) visualised under UV light after reaction with a spray of p-phenylene diamine, NH3 and molybdate. Solutions stored in a freezer are 2-3% hydrolysed in 3weeks. At 25o, only 4-6% hydrolysis occurs even in N NaOH or HCl, and 2% is hydrolysed at 37o in 1day-but is complete at 100o in 4hours. It is best stored as a dry solid at -20o. In aqueous acid the solution is colourless but is yellow in alkaline solutions. It has UV max at 305nm ( 1100) and 380nm ( 6550) in 0.1 N NaOH; 330nm ( 2450) and 388nm ( 4,900) in 0.05M phosphate buffer pH 7.0 and 295nm ( 6700) in 0.1N HCl. [Peterson et al. Biochemical Preparations 3 34, 119 1953.] The oxime decomposes at 229-230o and is practically insoluble in H2O, EtOH and Et2O. The O-methyloxime decomposes at 212-213o. [Heyl et al. J Am Chem Soc 73 3430 1951.] It has also been purified by column chromatography through Amberlite IRC-50 (H+) [Peterson & Sober J Am Chem Soc 76 169 1954]. [Beilstein 21/13 V 46.]
