Triphosphates are molecules that contain three phosphate groups linked together. They play a crucial role in cellular energy transfer, with the most well-known triphosphate being adenosine triphosphate (ATP). ATP serves as the primary energy currency in cells, providing the energy needed for various biological processes. In addition to ATP, other triphosphates, such as guanosine triphosphate (GTP), are also important in cellular functions. These molecules can release energy when one of the phosphate groups is removed, converting them into diphosphates. This energy release is essential for activities like muscle contraction, protein synthesis, and cell signaling.
