There are four compounds of the DNA (deoxyribonucleic acid), which are adenine, guanine, cytosine, and thymine. Among these four compounds, guanine and adenine are known to be made up of purine derivatives. The chemical formulas of purines are recognized with their double-ring structure.
Discussing the adenine now, it is a nucleobase that is derived from purines. It is known to be an organic compound present in both RNA and DNA. In addition, it is basically responsible for cellular respiration. It reacts with guanine to form nucleotides into a nucleic acid, and its chemical formula is C5-H5-N5.
On the other side of the coin, guanine is also recognized as a purine derivative. It is an essential component for DNA and RNA in the formation of nucleic acid. The major factor that makes its difference from adenine is its chemical formula, which is C5-H5-N5-O.
