Certain robust structural proteins are definitively classified as fibrous due to their massive, wate — Biomolecules Chemistry Question
Question
Certain robust structural proteins are definitively classified as fibrous due to their massive, water-insoluble parallel polypeptide chains heavily cross-linked together. Which of the following precise pairs strictly belong to this fibrous category?
Answer: B
💡 Solution & Explanation
Fibrous proteins like keratin (prominent in hair, nails, and wool) and myosin (essential in muscles) form rigid, highly insoluble linear fibres. Conversely, albumin, insulin, and haemoglobin fold tightly into spheres, rendering them highly water-soluble globular proteins.
