Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.

A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies.

Are proteins found in everything?

Your body needs protein to stay healthy and work the way it should. More than 10,000 types are found in everything from your organs to your muscles and tissues to your bones, skin, and hair.

What do proteins do in the body?

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

The three structures of proteins are fibrous, globular and membrane, which can also be broken down by each protein’s function. Keep reading for examples of proteins in each category and in which foods you can find them.

What are simple proteins?

Simple proteins. Simple proteins are made up of amino acid subunits joined together by peptide bonds. When hydrolyzed by enzymes, simple proteins yield only the amino acids from which they are comprised of. Examples of simple proteins include albumins, globulins, glutelins and albuminoids.
