Structure of Adenine

Adenine has a chemical formula of C5H5N5 and a molecular weight of 135.13 g/mol. It consists of a six-membered ring fused to a five-membered ring. The six-membered ring is composed of four carbon atoms and two nitrogen atoms. The five-membered ring contains three carbon atoms and two nitrogen atoms. The structure of adenine is often depicted as a hexagon attached to a pentagon.

Functions of Adenine

1. Genetic Information: Adenine pairs with thymine in DNA and with uracil in RNA, forming the base pairs that make up the genetic code.2. Energy Transfer: Adenine is a component of adenosine triphosphate (ATP), which is the primary energy carrier in cells. ATP releases energy when its phosphate groups are cleaved, providing energy for cellular processes.3. Signaling Molecules: Adenine is a component of cyclic adenosine monophosphate (cAMP), an important signaling molecule involved in various cellular pathways.
