Chemistry - The role of water

The role of water

In addition to the proteins, fats and carbohydrates in our diets, mineral
elements, vitamins, and water are also essential.

* Mineral elements are elements, other than C, H, O, and N that are found
as part of compounds in living organisms.

* Some have well known functions e.g. the link between calcium and
healthy bones, the link between lack of iron and anaemia. The active sites
[1] of many enzymes [2] include one or more mineral elements. An important
role of mineral elements is in maintaining a healthy nervous system,
especially through electrolyte levels and balances in the blood.

* Like mineral elements, vitamins have no energy value.

* Vitamins are important in controlling various aspects of the body's
metabolism but are not produced in our bodies and must be provided in our
diets.

* Some vitamins such as vitamin C (ascorbic acid) which is present in
fruits, green vegetables and potatoes, may have a preservative role.
Ascorbic acid acts as an antioxidant.
