MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

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. Answer: Keratin
