Proteins are large, complex chemical structure of hydrogen, oxygen, carbon, and nitrogen that play decisive roles in the regulation of the body’s tissues, organs and hormone secretion other than building muscles and loads of other functions. In fact protein is the most rich substance in your body after water – it is generally believed that human body consist of 50,000 different proteins.

Other function are – repairing red blood cells, growth of hair and fingernail, improving digestion, providing protection against different ailment, transporting nutrients to and from cells, carrying oxygen, controlling biochemical reactions and aiding the immune system and others. Protein can be found in plant sources such as beans, nuts and seeds as well as animal sources such as meat and dairy products. Every cell in your body contains protein which is why it is so significant to meet your protein requirement.

Repair and Maintenance

Protein is considered to be the building block of the body for its vital role in the maintenance developing and repairing of body tissue. The muscle repairing process require very good access to amino acids that is provided by your high-quality protein diet.

Strengthen immune system

Antibodies (believed to protects us from disease) are particular protein configurations that strengthen immune resistance against invaders. Such antibiotics are produced by our body once it comes into contact of antigens like bacteria, viruses and fungi and proteins is a watchful neighbour that support the immune system from behind as a next level of defence to protect you from illness, infection or disease. They work together make holes in bacterial walls, uphold inflammation to attack macrophages that obliterate foreign invading organisms.


Enzymes are proteins that accelerate chemical reactions in the body. Our body has to execute hundred different biochemical reactions ever day to function well and to perform perfectly it requires high level of energy and it’s protein known enzymes help the process to keep on thousands of times faster. For examples of enzymes are lactase and pepsin. Lactase facilitates the metabolism of lactose, milk and sugar and pepsin breaks down proteins in food in our small intestine to aid in digestion. Without enzymes, most basic physiological processes would proceed so slowly to support the life.

Enzymes are also very significant for biosynthesis – a multi-step, enzyme-catalyzed process of making new, complex molecules from the smaller subunits generated by the cell. Some biosynthetic enzymes are DNA Polymerase, fatty acid synthetase, and components of the ribosome.

Transportation and Storage of Molecules

Protein is a the key element in transportation of certain molecules throughout the body. Hemoglobin and cytochromes are examples. Hemoglobin is a kind of transport protein in red blood cells and it transports oxygen throughout the body and also a metabolic waste product carbon dioxide to lungs for emission from the body. Cytochromes helps as electron carrier proteins in the electron transport chain.

Protein is used to even store certain molecules including amino acids, ovalbumin, casein, ferritin. Casein is a milk-based protein and ovalbumin is found in egg whites. Ferritin is an example of a protein that stores iron in hemoglobin


A hormone is a chemical produced in one area of the body to communicate with the other parts or coordinate activities throughout the body. Protein helps creating some hormones for example Insulin and oxytocin are protein hormone that regulates blood sugar and stimulating contractions during childbirth. Hormones also initiate muscle growth by reducing protein breakdown and increasing protein synthesis. Another protein hormone is Secretin that helps to digest foods.

Excessive protein intake

When high quality protein in your diet is required, too much protein intake has its negative consequences on health. According to Janice R. Hermann, Ph.D., RD/LD of Oklahoma State University, excessive protein consumption can increase body fat, put extreme pressure on kidneys and liver. The best is to consult with a physician about your proper protein intake.
