The document is a presentation on minerals that defines minerals as essential elements present in nature that are important for the human body. It lists the objectives of defining minerals, elaborating their functions, and identifying types of minerals and how they change into ions. The presentation discusses how minerals function to build tissues, regulate fluids, assist functions, and form structures. Minerals are classified as macro minerals required in larger amounts and micro/trace minerals required in smaller amounts. It also explains how minerals dissolve in water to break into electrically charged ions. The major sections cover the major minerals calcium, phosphorus, potassium, sulfur, sodium, chloride, and magnesium, as well as the micro minerals iron, iodine, cobalt, copper, fluoride,

5. CLASSIFICATION OF MINERALS
Minerals are classified as Macro minerals (Major) and
Micro minerals.
1. Major minerals: These are required in amounts
greater than 100mg a day, sometimes called “macro
minerals”.
2. Trace minerals: These are required in the diet in
amounts lesser than 100mg a day - sometimes called

6. HOW MINERALS CHANGE TO IONS?
Ions: Ions are electrically charged atoms resulting from
chemical reaction.
Ions are divides into anions and cations. Anions are
negatively charged and cations are positively charged.
Mineral salts dissolve in water thus break into separate
ions known as electrolytes in such a condition.
