Proteins are large molecules built from small units known as amino acids. They are used for growth and repair, as well as for strengthening the bones. They help to make tissue and cells. They can be found in animals, plants, fungi, bacteria, and also in the human body. For example, muscles contain a lot of proteins. Body builders will eat foods with a lot of protein as an easy way to keep or gain high levels of muscles that is safer than taking steroids. Proteins form an important part in foods like milk, eggs, meat, fish, beans, and nuts. Animals eat proteins to get energy and amino acids. These amino acids are used to build new proteins that are used as enzymes, hormones, or antibodies. Protein is also very healthy and keeps you strong and makes your bones last. Proteins are essential for life.
"Proteins" were discovered by Berzelius, in 1838.
