Some enzymes have one or more sulfhydryl (thiol) groups that are important to enzymatic activity but that can react upon standing in solution to form inactive disulfide bonds. thiol reagents, such as 1,4-dithiothreitol (dtt), are often added to the solutions of such proteins to protect them from this reaction and to reverse it when it occurs. (the reverse reaction works best at slightly alkaline ph.) draw the product formed when dtt reacts with a protein disulfide bond to liberate the free thiol groups. which of the following occurs in this reaction? (check all that apply)the protein disulfide is oxidizedthe protein disulfide is reduceddtt is reduceddtt is oxidized

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

it's all four options.
