Collagen is:

  1. Globular protein
  2. Fibrous protein
  3. Carbohydrate
  4. Lipid

Answer

(2) Fibrous protein

Solution

As per NCERT, collagen is the most abundant protein in the animal world.

⇒ It is made of long polypeptide chains wound into a triple helix, forming tough fibres of connective tissue (tendons, ligaments, skin, bone).

∴ Collagen is a fibrous (structural) protein, not a globular protein.
