Deoxyguanine is one of the four nucleobases found in DNA, along with adenine, cytosine, and thymine. Its chemical structure consists of a purine ring connected to a deoxyribose sugar molecule. Synonyms for deoxyguanine include 2-amino-6-hydroxypurine, 2-amino-6-oxypurine, and 2,6-dioxopurine. It is often abbreviated as dG in scientific literature and is essential for the accurate replication and high fidelity transmission of genetic information from one generation to the next. Mutations that occur in the DNA sequence can result in a range of genetic disorders, making deoxyguanine and other nucleobases critical components of overall health and well-being.
