Chemistry - Biomolecules Question with Solution | TestHub

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

Fibrous proteins have a thread-like structure. Examples include keratin (present in hair, wool, silk) and myosin (present in muscles).

Globular proteins have a spherical shape. Examples include insulin, egg albumin, and serum albumin.

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