Which of the following describes a 'Fibrous Protein'?
Show answer and explanation
Correct answer: Elongated, thread-like shape and generally insoluble in water
Fibrous proteins such as collagen, alpha-keratin, and fibrin have elongated, thread-like or rope-like shapes and are generally insoluble in water. Their repetitive secondary structures (triple helices or coiled coils) are ideal for providing structural support and mechanical strength in connective tissues, hair, and nails.
