What Are The Functions Of Minerals In The Human Body?

Minerals have two main functions in the body. First of all, many minerals are responsible for building the structures in the body like bones, and teeth. Secondly, minerals help to regulate bodily processes.
Minerals can be classified into macroelements and microelements. Macroelements are those elements that are needed in relatively large amounts by the body and trace elements are those that are needed in small 'trace' amounts.
Some macroelements that are needed by the body are calcium,  phosphorous, magnesium, sodium, potassium, chlorine and sulfur. Both are needed for development of bones and teeth. Calcium is also important in regulating blood clotting, muscle tone and nerve function. Phosphorous helps in providing energy to work (ATP and ADP contain a phosphate-Adenosine TriPhosphate and Diphosphate).
Sodium is an osmoregulator (controls water potential) and also helps muscles to contract and relax. Potassium has similar functions but it is also responsible for regulating heart beat.
Chlorine is part of hydrochloric acid which is important for digestion of protein in the stomach and sulfur is an important constituents of all proteins (structural, enzymes, hair and nails).
The trace elements needed by the body and their uses are enlisted below:

• Iron - transport of oxygen in the blood
• Manganese - bones
• Iodine - regulates rate of metabolism
• Copper - facilitates absorption and function of iron
• Flourine - decreases tooth decay
• Zinc - important regulator
• Cobalt - a part of Vitamin B12
• Chromium - regulates glucose metabolism

List some sources of dietary mineral

MIneral elements are part of the human body's composition, and as they become used and depleted, they must be replaced.  The function of these minerals is in our nutrition.  (remember that mineral elements are found present in all living things.)

Some of those mineral elements include sodium, potassium, calcium, phosphorus, magnesium, sulfur, iron and copper, chlorine, iodine and fuorine, zinc and manganese (1, 3, 12, 33). Additional elements that are present in small amounts include aluminum, arsenic, and boron.  Each mineral serves various purpose in the ability of our body to function.  Calcium is the main element of which bones are comprised, for example.  Sulfur is a mineral that is a cofactor for
enzymes of glycoprotein and proteoglycan synthesis in our bodies.  Iron  is used in oxygen
transport and storage, oxidative reactions and the electron transport chain.

Minerals or Dietary Minerals are the chemical elements which are required by the living organisms. Dietary minerals are found in abundance in natural food items. Following are the functions of Dietary Minerals:

- They support biochemical reactions.

- They are required for maintaining optimal health.

- They play a key role in cell structure and function.

- They act as co-factors in enzyme functions.
