Procedure

Uric acid is oxidized enzymatically by uricase to allantoin and hydrogen peroxide at about pH 7. The stoichiometry of the enzyme reaction proper, regardless of buffer or pH, is given by equation (1), i.e., the transfer of an electron pair from the urate monoanion to oxygen, yielding an unstable acid intermediate (1-carboxy-2,4,6,8-tetraazabicycl [3,3,0]-octa-4-en-3,7-dione), and hydrogen peroxide.
