Chemistry - Biomolecules Question with Solution | TestHub

Proteins are classified into two types based on their molecular shape: globular proteins and fibrous proteins.

Globular proteins have a spherical shape resulting from the coiling of the polypeptide chain. They are usually soluble in water. Examples include insulin, egg albumin, and legumelin.

Fibrous proteins have an elongated, rod-like shape where polypeptide chains run parallel to each other and are held together by hydrogen and disulfide bonds. They are insoluble in water. Examples include keratin and myosin.

Therefore, myosin is a fibrous protein and not a globular protein.

Answer: Myosin
