Phosphate is a containing a phosphorus atom. Its chemical formula is HPO.
When heated (perhaps on the side of some ancient volcano on the young ) phosphate molecules can join together by to form chains.
Phosphate is an . When placed in water it looses a it becomes . In a chain of phosphates, each phosphate can loose become charged. These charges repel each other. But the is stronger than the force of repulsion, so the chain does not break apart. Instead it gains springiness in the bond between phosphates.
This spring is the driving force of many of life’s processes. Phosphate is used by to carry from one to another in . It is also part of and .
Because it is part of the fundamental molecules of life, we can be fairly sure phosphate was used when life was first evolving, soon after the Earth was formed.
