Question

Certain highly abundant proteins are completely water-insoluble and physically feature massive polypeptide chains running precisely parallel to each other, rigidly held firmly together by extensive intermolecular hydrogen and covalent disulfide bonds. These proteins are strictly classified as:

Prashant Kotian · Accepted Answer

Correct answer: C. Fibrous proteins severely lack solubility in standard aqueous biological solutions because their long, highly stretched peptide chains securely cross-link heavily to form vast dense parallel fibers. Classic examples include tough structural components like keratin (hair) and myosin (muscle).
