Uric Acid
Purines perform multiple important functions within our cells, including regulating energy metabolism and signaling the energy conversion from one to another. Purines are essentially the building blocks for all living things as a necessity for the growth, proliferation and survival of all cells. The two purine bases, adenine and guanine, create bonds that form the DNA ladder. Humans breakdown purines and convert them into uric acid.
Uric acid happens to be a potent DNA protector. All other mammals possess an enzyme known as uricase. Uricase converts uric acid into allantoin, which can easily travel through the bloodstream and readily eliminated through the urine. Humans do not possess this enzyme, therefore, we cannot oxidize uric acid into the more soluble compound of allantoin. Our liver and kidneys are left to do the all-important jobs of purine breakdown and uric acid disposal, conducted respectively.
