Firstly, we have to understand where uric acid comes from. Animal cells (including human cells) have structures called DNA, which reside with the nucleus of the cell. This DNA is broken down into its constituents, called amino acids, when a cell dies through the action of the immune system. Some of these amino acids are called purines, which in turn are converted into other chemicals. Our body recycles some of these chemicals with those left over proceeding to become uric acid, which is in some ways a waste product that is then excreted by our kidneys into the urine.
