Protein is crucial to good health.

In fact, the name comes from the Greek word proteos, meaning “primary” or “first place.”

Proteins are made up of amino acids that join together to form long chains. You can think of a protein as a string of beads in which each bead is an amino acid.

There are 20 amino acids that help form the thousands of different proteins in your body.

Proteins do most of their work in the cell and perform various jobs.

Here are 9 important functions of protein in your body.

• Your body needs protein for growth and maintenance of tissues.
• Yet, your body’s proteins are in a constant state of turnover.
• Under normal circumstances, your body breaks down the same amount of protein that it uses to build and repair tissues. Other times, it breaks down more protein than it can create, thus increasing your body’s needs.
• Enzymes are proteins that aid the thousands of biochemical reactions that take place within and outside of your cells.
• The structure of enzymes allows them to combine with other molecules inside the cell called substrates, which catalyze reactions that are essential to your metabolism. Enzymes may also function outside the cell, such as digestive enzymes like lactase and sucrase, which help digest sugar.
• Some enzymes require other molecules, such as vitamins or minerals, for a reaction to take place. Some proteins are hormones, which are chemical messengers that aid communication between your cells, tissues and organs.
• They’re made and secreted by endocrine tissues or glands and then transported in your blood to their target tissues or organs where they bind to protein receptors on the cell surface.
• Some proteins are fibrous and provide cells and tissues with stiffness and rigidity.
• These proteins include keratin, collagen and elastin, which help form the connective framework of certain structures in your body.
