Adenosine vs. Deoxyadenosine: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 19, 2024
Adenosine is a nucleoside important in energy transfer, while deoxyadenosine is its deoxyribose-containing variant, essential in DNA structure.

Key Differences

Adenosine is a nucleoside composed of an adenine base attached to a ribose sugar, playing a crucial role in cellular energy transfer, neurotransmission, and signal transduction. Deoxyadenosine differs by having a deoxyribose sugar instead of ribose, making it a fundamental component of DNA, where it pairs with thymine.
