Protein is an abundant substance found in the human body which is to perform many functions in the body. It is found in each cell, so it is vital to replenish protein in the body for it to function properly. What exactly are the functions protein provides to the body and what foods can you consume to ensure you are getting the proper amount? Read on to answer these questions.

What Are the Functions of Protein?

1. Structure

Protein is found in many structural components in the body. It is found in the membranes of cells, hair, skin, tissues, muscles and most of the organs in the body. Protein is what helps strengthen all these factors and allows for the body to be able to move properly. From contracting muscles movements to bowel movement, protein plays a major role in the structure of the body.

2. Biochemical reactions

The protein enzymes enable biochemical reactions that take place in the body. This has an effect on the nervous system, the digestive process and even breathing. Protein enzymes help drive different reactions in the body to happen faster. This is vital in the metabolism of turning the food you consume into energy your body needs to function normally.

3. Hormones

Hormones have a number of effects on the body and begin to play a significant role during puberty. There are some proteins that are hormones and assist in regulating the menstrual cycle in women and sperm production in men. These hormones also have an impact on muscles mass, hair growth, and your mood. Protein is necessary to balance hormone levels throughout your life and affect the aging process as you move through the different stages in life.

4. Cell division

Cell division is a vital process that occurs when aged or damaged cells need to be replenished or replaced. One of the functions of protein is to regulate this process. When cells become damaged over time from excess sun exposure or harmful toxins or substances in the environment, healthy cells will divide into copies. Protein is used to regulate this division and growth of new cells. Without the proper amount of protein, the cell division can cause the growth of tumors, which may lead to cancer.

5. Immune system

The antibodies found in the immune system are a type of protein that keeps you healthy. The immune system is responsible to fight off bacterial and viral infections. There are a variety of antibodies in the immune system and each has their own structure that is designed to invade specific types of bacteria and viruses. Once these antibodies have bound itself to a harmful bacteria or virus, it sends a signal that these invaders need to be destroyed.
