Globular proteins are a type of protein commonly found in all living organisms. Their functions range greatly and are one of two types of protein. Globular proteins are known for their complex structure, which results in a very spherical (globular) shapes. They are made of polypeptide chains folded into a compact sphere shape. They are soluble in water because of the hydrophilic side chains that project from the outside of the molecules. They play an important role in metabolic reactions.

A few examples of globular proteins include enzymes, myoglobin and hemoglobin.
