Pyrophosphate

Pyrophosphate (pronounced: py-roh-FAHS-feyt) is a type of phosphate that consists of two phosphorus atoms and four oxygen atoms. It is an important molecule in biochemistry and molecular biology, playing a key role in many biological processes.

Etymology

The term "pyrophosphate" comes from the Greek words "pyro," meaning fire, and "phosphate," referring to a salt or ester of phosphoric acid. The name reflects the compound's formation through the heating (or "burning") of phosphate.

Biochemical Role

In biochemistry, pyrophosphates perform a variety of functions. They are involved in the synthesis of DNA and RNA, where they serve as the building blocks for these important molecules. Pyrophosphates also play a role in energy transfer within cells, as they are a component of adenosine triphosphate (ATP), the main energy currency of the cell.
