[The inhibition of the peroxydatic activity of human ferricyanohemoglobin (guaiacol-H2O2 system) by syringic acid].
A structural analog of gaiacol, syringic acid behaves like a competitive inhibitor to the peroxydatic activity of human ferricyanohemoglobin with other substrates (gaiacol system-H2O2). An outline which takes into account this double competition is proposed and discussed.
