Vedclass · Answer

(B) The $\alpha-$amino acid that forms cross-links in peptide chains is $Cysteine$. $Cysteine$ contains a thiol group $(-SH)$ in its side chain. Two $Cysteine$ residues can undergo oxidation to form a disulfide bond $(-S-S-)$,which acts as a cross-link between different parts of a protein chain or between different polypeptide chains,stabilizing the tertiary structure of proteins.
