What Are Proteins? Why Protein Is Essential For Human Body?

Protein is a nutritional compound; our body needs to grow and repair cells to work effectively. People who take high protein meals are healthy, hold good strength and stamina, and have good hair quality. Protein is the essential substance found in many of our everyday foods like eggs, green veggies, pulses, fish, etc. It is essential to have sufficient protein in your everyday diet. 

Scientific Definition Of Protein

Protein is made up of building blocks in the body known as amino acids. In a human being, approximately 20 different amino acids are associated with each other and provide different combinations. Our body utilizes these chemicals to create new proteins like muscles, bones, and other necessary compounds, including enzymes and hormones. 

Why Is Protein Necessary For Human Body?

The human body needs every compound in a definite amount. Speaking of protein, the nutritional value of protein in an individual is analyzed from the number of amino acids it contains. There are a few reasons why you need protein for the human body.

1. Growth & Maintenance

The first need to have protein compounds in the body is to provide necessary growth and maintenance to the individual body. The human body breaks down the same quantity of amino acids it utilizes to build or repair cells and tissues in a general health state. 

But when we fall sick, injured, or have health issues, we need more protein than usual to regenerate or repair the cell and tissues. Thus, an individual needs healthy high protein meals to obtain such resistance in the body. 

2. Biochemical Reactions

Enzymes are another form of protein that helps build biochemical reactions within and outside the cell. The formation of enzymes aids them in combining with other molecular particles, known as substrates. It catalyzes the reactions and induces metabolism. 

Simultaneously, enzymes can perform their functions outside the cells like digestive enzymes Lactase and Sucrase, which helps them digest the sugar quickly. Other enzymes need other molecules like vitamins and minerals to form reactions for proper functioning in the human body. 

3. Protein Acts As A Manager

There are a few proteins termed hormones that regulate communication between cells, tissues, and organs in an individual. They are the chemical messenger to establish a proper conversation between different organs and cells. The proteins are made of endocrine tissues or glands and transported to the blood vessels of the human. It then targets tissues or organs, holding together protein receptors on the cell surface. 

4. Provides Structure

Other protein facts include fibrous proteins and give cells and tissues the required stiffness and rigidity. Such popular proteins are keratin, collagen, elastin, etc., which help form the bounding framework of specific structures in the human body.

Keratin is a common protein found on an individual's skin, hair, and nails. Collagen is found in abundance and builds bones, tendons, ligaments, and skin. The next one is elastin, which is more flexible than collagen. Its elasticity allows many tissues to reach their original form and shape in matters of stretching and contracting, like the uterus, lungs, arteries, etc. 

5. Balancing Fluid 

Proteins help in balancing the fluids in the body and regulate the process. There are two types of protein known as Albumin and Globulin. These help in maintaining the fluid balance by attraction and retention of water. People with low protein levels lose these compounds and eventually the balanced fluid. 

Furthermore, an insufficient quantity of Albumin and Globulin reduces blood vessels' blood, and the fluid is forced to get cultivated between the cells. 

Now that we have seen it, why is protein essential? Let us get back to the list of the top 10 foods with high protein.
