What is a Adenine (chemical formula: C₅H₅N₅)?

Adenine (chemical formula: C₅H₅N₅) is a purine base and one of the four nucleobases found in DNA and RNA. It plays a critical role in storing and transmitting genetic information, pairing with thymine (T) in DNA and with uracil (U) in RNA through hydrogen bonding. Adenine is also a key component of biologically essential molecules such as ATP (adenosine triphosphate) and NAD (nicotinamide adenine dinucleotide), which are involved in energy metabolism and redox reactions within living organisms.

It appears as a white or slightly yellow crystalline powder, poorly soluble in water but more soluble in acidic or basic solutions. As a fundamental unit of life, adenine is widely studied in molecular biology, genetics, and biotechnology.

While generally considered safe for laboratory use, it is recommended to use gloves and a mask to prevent inhalation or skin contact.
