Disulfide bond
C
Hydrogen bond
D
Ionic bond
Verified step by step guidance
1
Identify the functional groups involved in the formation of the bond. In this case, we are dealing with sulfur-containing chains, which typically involve thiol groups (-SH).
Understand the nature of the bond formation. When two thiol groups come together, they can form a disulfide bond through an oxidation reaction.
Recognize that a disulfide bond is a covalent bond formed between two sulfur atoms, typically from cysteine residues in proteins.
Differentiate between the types of bonds listed: Peptide bonds link amino acids, hydrogen bonds are weak interactions between polar molecules, and ionic bonds occur between charged ions.
Conclude that the bond formed between two sulfur-containing chains is a disulfide bond, as it involves the covalent linkage of two sulfur atoms from thiol groups.
