Life depends on an incredible enzyme called ATP synthase, the world’s tiniest rotary motor.1 This tiny protein complex makes an energy-rich compound, ATP (adenosine triphosphate). Each of the human body’s 14 trillion cells performs this reaction about a million times per minute. Over half a body weight of ATP is made and consumed every day!

All living things need to make ATP, often called the “energy currency of life”. ATP is a small molecule with a big job: to provide immediately usable energy for cellular machines.
