Adenosine Di-Phosphate (ADP)
Adenosine Di-Phosphate is the product of ATP (Adenosine Tri-Phosphate) break down. When one of the bonds that attaches the phosphates to the adenosine molecule breaks, it releases energy. The by-product of this energy is an adenosine molecule with only two (di) phosphates attached.
The body recycles ATP by combining ADP with phosphocreatine, ensuring we have an enduring energy supply.
