Inorganic ions include those of sodium

Medically, inorganic ions may also be known as electrolytes.

Sodium ions are also involved in the passage of nervous impulses along the axon of a neuron, and at synapses between them. Ions are particles atoms or groups of atoms that have an electrical charge due to gaining or losing electrons. They regulate cellular homeostasis and are important in modulating important body processes such as nerve signalling, muscle contractions and water balance.

Ions are also incorporated into the structure of biological molecules. In fact they build up in the spaces between the inner and outer membranes, and their concentration is used to produce ATP - the energy currency of the cell. Interestingly there are some similarities with haemoglobin: Catalase is a tetramer of four polypeptide chains, and it contains four haem groups containing iron.

In fact, pH is calculated based on the concentration of hydrogen ions in a solution, the more hydrogen ions there are, the more acidic the solution is.

Anions Anions are negative ions. Maintaining the correct pH of bodily fluids and cells is also crucially important, a slightly acidic blood pH even just pH 6.

inorganic ions in the body

These are found in a variety of places - in the sea and our bloodstream.
