Identify the true statements regarding disulfide bridges (disulfide bonds). Disulfide bridges have a stabilizing effect on proteins. Disulfide bridges are formed by an irreversible oxidation reaction. Disulfide bridges can exist between two amino acid residues on different chains. A disulfide bridge forms between two cysteine residues. Disulfide bridges are important to primary and secondary structure.

The answer is 1,3,4

Explanation:

I got it right on the homework

Option (1), (2), and (4).

Explanation:

A disulphide bond is also known by the name disulphide bridge. This is a type of a covalent bond by the oxidation of the sulfhydryl groups. This bond is important for the folding of proteins.

Disulfide bonds is important for the stabilization of protein. Their main effect is to stabilize and the proper functioning of protein. The disulfide bond is present between the two amino acids of the different polypeptide chain. The amino acids that contain cysteine residues has the ability to form this bond.

Thus, the correct answer is option (1), (2), and (4).
