The word mineral literally means 'mined from the earth'. They can be divided into two main groups, metallic and non-metallic elements. Carbohydrates, fats, proteins and vitamins are all based on the element, carbon, and are known as organic substances. Minerals do not contain carbon and are said to be inorganic.
