Adenosine Triphosphate (ATP)

Adenosine triphoshate (ATP) is the bodies universal currency for energy. In fact it is the only fuel that the body can use. It is responsible for all muscle contraction, repair and growth of tissues.

Structure of Adenosine Triphosphate (ATP)

ATP is comprised of one adenosine molecule and and three phosphate molecules. When one of the phosphate molecules is released and ATP becomes ADP (adenosine diphosphate) this in turn releases energy.

We have a very limited store of ATP in our bodies so we have to continually resynthesise it. This is called the ATP cycle. We can do this via the breakdown of phosphocreatine, carbohydrate, fat or protein.
