Answer 2

True Cysteine is a sulfur-containing polar amino acid, but Cystine is a nonpolar dipeptide derived from two cysteine amino acid residues linked together by a disulfide bond.

• Cysteine is an important amino acid that helps in the formation of sulfide bonds. It is polar in nature as it consists of a thiol group.
• Cystine formed by the joining of two cysteine residues linked by a disulfide bond is a non-polar dipeptide as disulfide-linked residues are highly hydrophobic.
• Cystine helps in the stabilization of many proteins.
