Explain any 4 micro nutrient in …

Micronutrients, i.e., vitamins and minerals can be divided into the following types:

Water-Soluble Vitamins

Most of the vitamins can be dissolved in water. They are difficult to store in the body and get flushed out in urine when consumed in large quantities. They play an important role in producing energy. Since they are not stored in the body, it is important to take them enough from different food sources.

Fat-Soluble Vitamins

These vitamins do not dissolve in water. These are stored in the liver and fatty tissues for future use. Vitamins A, D, E, and K are important fat-soluble vitamins. They play a major role in the proper functioning of the immune system, proper bone development, proper vision, and protection of cells from damage.

Macrominerals

These are required in higher amounts as compared to the trace minerals. The important macrominerals and their functions include:

• Calcium- For the proper structure and function of bones.
• Phosphorus – Cell membrane structure
• Magnesium- Enzyme reactions
• Sodium- Fluid balance and maintenance of blood pressure
• Chloride- Maintains fluid balance and formation of digestive juices.
• Potassium- Nerve impulse transmission and muscle function.
• Sulphur- present in all the living tissues

Trace Minerals

These are required in very small amounts, but perform various important functions in our body. Iron, manganese, copper, zinc, iodine, fluoride, and selenium are some of the important trace minerals required by the body.
