검증된 단계별 안내1
Understand that disulfide bonds in proteins are covalent bonds formed between the side chains of specific amino acids through oxidation.
Recall that disulfide bonds specifically form between the thiol (-SH) groups of cysteine residues, linking two cysteine molecules to form cystine.
Recognize that among the given options, only cysteine contains a thiol group capable of undergoing oxidation to form a disulfide bond.
Note that asparagine, serine, and threonine have polar side chains but lack the thiol group necessary for disulfide bond formation.
Conclude that cysteine is the polar amino acid responsible for forming disulfide bonds in proteins through oxidation of its side chain.
