The xanthine oxidase and its associated activities in the ovine milk and liver: distinctive in impact of in vivo molybdenum

Xanthine oxidase is molybdenum and iron-containing flavoprotein, catalyzing the final oxidation stage of purines oxidative transformation pterins some aliphatic aromatic aldehydes. Despite importance this enzyme, distribution xanthine in traditional household animal’s milk tissues unknown. Formerly, we have found most molecules animal are inactive because a lack molybdenum. Ovine was processed by inserting vivo (tungsten) into drinking water. We gave opposite dates presence tungsten too. Heating animals at 80 °C for 5 minutes cysteine led to sharp increase its associated – nitrate reductase nitrite activities. The change activities were examined spectrophotometry after treatment. It established that metal ions added water an impact on enzyme activity formed ovine liver even absence exogenous enzymes had slightly increased. Tungsten-containing loss all oxidase. proposed contains special protein involving incorporation (or tungsten) molecule, however, or mammary gland compounds protein.
