Chemistry - Biomolecules Question with Solution | TestHub

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

Fibrous proteins have a fiber-like structure formed by parallel polypeptide chains held together by hydrogen and disulfide bonds. Examples include keratin (found in hair, wool, silk) and myosin (found in muscles).

Globular proteins have a spherical shape formed when the chains of polypeptides coil around. Examples include insulin and albumins.

Thus, insulin is a globular protein.
