Diadenosine tetraphosphate or Ap4A is a putative alarmone, ubiquitous in nature being common to everything from bacteria to humans. It is made up of two adenosines joined together by a 5′-5′ linked chain of four phosphates. Adenosine polyphosphates are capable of inducing multiple physiological effects.
