Phosphorus is an important element in biological systems and is normally present as part of a phosphate group. Phosphate groups come from phosphoric acid (H₃PO₄). The phosphate groups may be alone, part of a diphosphate, part of a triphosphate, or part of a phosphate ester.

Phosphates are in teeth and bone, and are a part of the energy transport molecules ATP and ADP (see Chapter 12 for more on these molecules). Figure 3-5 illustrates phosphorous-containing functional groups.
