Adenine derivatives are chemical compounds that are related to the base adenine, which is one of the building blocks of DNA and RNA. These derivatives can have various functional groups attached to the adenine structure, altering its properties and functions. They play crucial roles in biological processes, such as energy transfer and signaling within cells. One well-known adenine derivative is adenosine triphosphate (ATP), which serves as the primary energy currency in living organisms. Other derivatives, like caffeine and theophylline, are found in plants and can affect human physiology, influencing alertness and relaxation. Understanding these derivatives helps scientists explore their potential therapeutic applications.
