Uric acid is end product of Purine metabolism by xanthine oxidase and other enzyme and is responsible for uric acid production coupled with production of free radicals superoxide (O^2-), which contribute to oxidative stress on endothelial lining of arteries .These may contribute to development of gestational hypertension.
