Comparism Of Xanthine Oxidase Activities In Cow And Goat Milks|
Egwim, Evans C.; Vunchi, Mohammed A. & Egwim, Patience O.
The activities of xanthine oxidase were studied in cow and goat milks. The optimum temperature and pH values were 10 °C and 7.5; and 20 °C and 7.2 - 7.4 for cow and goat milk samples respectively. The substrate effect on xanthine oxidase from both milk samples followed the popular Michealis Menten's (Km) equation. The Km and V max were 0.86 x 10-2 M and 3.7 Msec-1 and 4.36 x 10-2 M and 2.0 Msec-1. The work concludes that xanthine oxidase from cow and goat milk differs both in their basic characteristics and in the kinetic activities.
