$\alpha$-keratin

Vedclass · Answer

(A) $\alpha$-keratin is a fibrous protein. Fibrous proteins are characterized by long,thread-like structures that are held together by hydrogen bonds and disulfide bridges. Due to their highly ordered,repetitive structure and the presence of hydrophobic amino acid residues,they are generally insoluble in water. In contrast,hemoglobin and ribonuclease are globular proteins,which are typically soluble in water. Adenine is a nitrogenous base that has limited solubility but is more soluble than fibrous proteins like keratin.
