Purine Bases and Uric Acid Separation (GS-320 HQ)
Purine base and its final metabolite, uric acid, were separated using multi-mode column, Asahipak GS-320 HQ
Purine base is a general name for compounds (nucleotide, nucleoside, base) containing purine structure and found in most foods. Through metabolic pathways, purines are broken down to uric acid, when exceeded amount of uric acid is accumulated in body, it may cause gout.
For the analysis of purines in food, first, homogenized food is freeze-dried and then dissolved in 70%H2
. By this hydrolysis process neutralizes the purines into purine bases.
