Examples of Proteins

Hemoglobin is a protein found in red blood cells that help regulate oxygen throughout the body. Insulin is also a protein that helps regulate the amount of sugar in the blood.

Functional Groups Found in Protein

One of the functional groups found in protein is a carboxyl group. Another is an amine.

Common Functions of Protein

Proteins are used as transport molecules. For example, hemoglobin helps transport oxygen. They are also used as storage molecules. For example, iron is stored in the liver with the help of the protein ferritin. They are used in movement as well. For example, proteins are a major component in your muscles.

How Does the Structure of Protein Allow for its Function?

The function of a protein is determined by its shape. The shape tells the proteins what molecules it can interact with. The structure also determines the folding pattern of the molecule.
