Micronutrients

Nutrients

The nutrients are substances used by an organism to survive, grow, and reproduce. Different types of organisms need different essential nutrients. According to Its needs of animals divide nutrients into macronutrients and micronutrients. Macronutrients are commonly used in a relatively large amount. Carbohydrates, proteins, fats, etc are examples of macronutrients. Micronutrients are commonly used in a relatively smaller amount. Different types of vitamins, minerals are the main examples of micronutrients.

Nutrients

In the sense of essentiality of human beings types of macronutrients and their function is a relatively simple task than micronutrients so only micronutrients are being described here.

Micronutrients

Different types of vitamins and minerals are essential micronutrients for human which are mentioned below:

Vitamins

Vitamins are very important organic essential micronutrients of our food. Essential nutrients can not be synthesized in organisms, therefore, must be obtained through the diet. Which an organism needs in small quantities for the proper functioning of its metabolism. On the basis of solubility, vitamins can be divide into two groups-

1. Fat-soluble vitamins

Vitamins A, D, E, and K are fat-soluble vitamins. These can be stored in fat tissue and the liver for a long time.

2. Water-soluble vitamins

Vitamins B-complex and C are water-soluble vitamins. These can not be stored for a long time because excess amount of its with the urine these excrete from the body.

micronutrients
Functions, dietary effects, chemical names,s and food sources of these vitamins are mentioned in this chart.
