Given below is a list of the functions that protein is responsible for performing within your body.

Maintenance and growth

The body requires protein in order to grow healthy as well as maintain the tissues. Under any normal circumstances, your body is capable of breaking down a similar protein quantity, which is used for building and repairing the tissues. Most of the times, it breaks down a lot more protein than what is created, thereby increasing the need of the body. This is known to happen mostly during illness, pregnancy, as well as when you are breastfeeding your baby. People who are trying to recover from any kind of injury or surgery also require a good quantity of protein. If there is any problem in your body, doctors can suggest antibody purification.

Responsible for biochemical reactions

Enzymes are basically proteins, which are responsible for helping in numerous biochemical reactions, which take place both inside as well as outside the cells. The unique structure of each and every enzyme helps them in combining with various other molecules, which are known as substrates, and this helps in catalyzing the reactions, which are mandatory for the metabolism of the body. Enzymes can also function in other places like sucrase and lactase, which help in digesting sugar. Functions that are responsible for depending on the enzymes include:

  • Digestion
  • Production of energy
  • Clotting of blood
  • Contraction of muscles
  • Acts like a messenger

Few proteins are also hormones, which are basically chemical messengers, which help in increasing communication between the cells, organs, and tissues. They are made as well as secreted by the endocrine tissues, which are transported into the blood for targeting organs and tissues, where they will bind to the protein receptors present on the surface of the cell. Hormones include three categories, protein and peptides, steroids, and amines. Polypeptides and proteins are responsible for making up most of the hormones of the body.  

Helps in providing structure

Few proteins have a fibrous structure and they are responsible for providing the tissues as well as cells with rigidity and stiffness. These proteins are also responsible for including keratin, elastin, and collagen, which help in forming a connective framework of different structures in the body. Keratin is the structural protein, which is found in the skin, nails, and hair. Collagen is found in bones, skin, ligaments, and tendon. Elastin is found in different tissues and it is more flexible in comparison to collagen.


Proteins play a crucial role within your body and it is important that you make sure to take a protein-rich diet.
