WebMar 1, 1985 · Horseradish peroxidase catalyses the oxidation of NAD dimers, (NAD)2, to NAD+ in accordance with a reaction that is pH-dependent and requires 1 mol of O2 per 2 mol of (NAD)2. Horseradish peroxidase also catalyses the peroxidation of (NAD)2 to NAD+. In contrast, bacterial NADH peroxidase does not catalyse the peroxidation or the oxidation … WebPeroxidase is a common, heat stable enzyme that is found in plants and plant products, including fruits, vegetables and grains. …. There is a direct relationship between the peroxidase activity and the development of off-flavours, off-odours and off-colours in food (Burnette, 1977).
