Protein Stability Attractive Vander Waals forces occur between polar molecules in the solid state any pair of nearby atoms only if other forces are less favorable apolar molecules in the liquid state polar molecules in the solid state any pair of nearby atoms only if other forces are less favorable apolar molecules in the liquid state ANSWER DOWNLOAD EXAMIANS APP
Protein Stability The correlation between free energy ΔG transfer between the aqueous/organic phases and the surface area of amino acid residues ignores the important contribution of the peptide bond is only meaningful for the polar amino acids reflects the reduction in solvent-accessible area during protein folding is similar to effects seen with SDS denaturation ignores the important contribution of the peptide bond is only meaningful for the polar amino acids reflects the reduction in solvent-accessible area during protein folding is similar to effects seen with SDS denaturation ANSWER DOWNLOAD EXAMIANS APP
Protein Stability For the unfolding reaction of Protein G, ΔH° =210.6 kJ/mol, this means that the entropy is negative at all temperatures folding is favored enthalpically unfolding is favored enthalpically the entropy is positive at all temperatures the entropy is negative at all temperatures folding is favored enthalpically unfolding is favored enthalpically the entropy is positive at all temperatures ANSWER DOWNLOAD EXAMIANS APP
