The role of protein in the human body

Fish is a great source of protein. Source Vital Chemicals Proteins are vital components of our bodies. Protein molecules are made of chains of amino acids. Our bodies digest the proteins that we eat, converting them into individual amino acids that are absorbed into the bloodstream.

Proteins do more in your body than just help build strong muscles. They are present in every cell and tissue, each one with a highly specialized function necessary for normal development and function with no one role more important than the others.

You obtain most of the protein your body uses through your diet, but your body can make proteins as well. Structure Proteins can consist of a single chain of less than amino acids up to a complex structure of several chains with hundreds of folds and a three-dimensional shape.

These larger proteins, called structural proteins, provide structure and shape to cells, organs and connective tissue. Muscle Contraction Actin and myosin are two specialized types of filament protein present in your muscle. When stimulated by a signal from the central nervous system, these two proteins act in unison to shorten in length, causing your muscle to contract.

Immunity Antibodies, another protein, help your body fight infection. For each antigen that enters your body, you have a separate and distinct antibody to fight it.

Antibodies immobilize and sequester antigens until white blood cells can destroy them. Enzymes Your body performs thousands of biochemical reactions a day to function properly. These reactions require energy, and many have significantly high energy thresholds that can delay essential reactions.

Proteins called enzymes assist in lowering the activation energy of hundreds of reactions, helping them to proceed thousands of times faster than they would in a normal environment.

A well-known example of an enzyme is lactase, which facilitates the metabolism of lactose, or milk sugar, in your small intestine to aid in digestion. Hormones Hormones are proteins that send signals and coordinate activities throughout the body.

Vital Chemicals

Examples include insulin, which facilitates glucose metabolism and controls blood glucose levels; thyroid hormones, which regulate metabolism, body temperature and the synthesis of other proteins; and gonadotropins, which stimulate the production of sperm and ova.

Transport Transport proteins carry other proteins and compounds throughout the body. Hemoglobin is a type of transport protein present in red blood cells; it carries oxygen from the lungs to all tissues and cells and transports carbon dioxide, a metabolic waste product, back to the lungs for excretion from the body.

Energy Your body can use protein for its energy needs when carbohydrates are depleted. When needed, proteins degrade into their component amino acids, which are then oxidized in the same process as glucose to create energy.Hemoglobin is a type of transport protein present in red blood cells; it carries oxygen from the lungs to all tissues and cells and transports carbon dioxide, a metabolic waste product, back to the lungs for excretion from the body.

Apr 20,  · One of the main functions of protein is tissue growth. Each cell and tissue in your body contains thousands of proteins, and the amino acids you get from your diet ensures your body can make the proteins it needs to keep those tissues strong.

Other than water, proteins are the most abundant type of chemical in the human body.
