Purines are the larger of the two types of bases found in DNA. Cytosine and thymine are pyrimidines. The deoxyribose sugar of the DNA backbone has 5 carbons and 3 oxygens. The carbon atoms are numbered 1', 2', 3', 4', and 5' to distinguish from the numbering of the atoms of the purine and pyrmidine rings.
Be it a cola, non-cola, diet soda or other sugar-sweetened carbonated beverage, carbonated beverages can increase your risk of serious health issues. Soda, especially colas, contains high levels of phosphoric acid, which is closely linked with the development of kidney stones and other renal problems.
Probably what causes the most abuse to the kidneys are: COFFEE, TEA AND SODA. Some people think that it's the caffeine in these drinks that is hard on the kidneys and joints. Caffeine is not good for you, but it is the tannic acid that damages the kidneys. Another real offender is artificial colored sugar water. Carbonation is also very hard on the kidneys.
