Purine bases and their nucleotides are captured by the liver and converted into xanthines, metabolized by UA, or recycled by salvage pathways or de novo synthesis. UA formation by xanthine occurs via hypoxanthine by the action of xanthine oxidase (XO), an enzyme present in the peroxisomes of most cells, which is an im-portant source of reactive oxygen species involved in various forms of ischemic and other types of vascular injuries and chronic heart failure. ....
