abstract：:Oxidation of rainbow trout haemoglobin (Hb) by nitrite proceeded via an initial lag phase followed by autocatalysis when the O2 saturation of the Hb was high. At low O2 saturations, the rate of methaemoglobin (metHb) formation was strongly reduced and autocatalysis was absent. Addition of adenosine triphosphate and gu...
