Protein Stability The correlation between free energy ΔG transfer between the aqueous/organic phases and the surface area of amino acid residues reflects the reduction in solvent-accessible area during protein folding ignores the important contribution of the peptide bond is similar to effects seen with SDS denaturation is only meaningful for the polar amino acids reflects the reduction in solvent-accessible area during protein folding ignores the important contribution of the peptide bond is similar to effects seen with SDS denaturation is only meaningful for the polar amino acids ANSWER DOWNLOAD EXAMIANS APP
Protein Stability Unpaired H-bond donors and acceptors are found in the hydrophobic core of a protein only at the ends of a-helices only at the turns connecting p-strands rarely only on Pro residues only at the ends of a-helices only at the turns connecting p-strands rarely only on Pro residues ANSWER DOWNLOAD EXAMIANS APP
Protein Stability At the midpoint of a temperature transition curve, All of these half of the protein is denatured Keq = 1.0 and ΔG = 0 [Native] = [Unfolded] All of these half of the protein is denatured Keq = 1.0 and ΔG = 0 [Native] = [Unfolded] ANSWER DOWNLOAD EXAMIANS APP
Protein Stability For the unfolding reaction of Protein G, ΔH° =210.6 kJ/mol, this means that 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 the entropy is negative at all temperatures folding is favored enthalpically ANSWER DOWNLOAD EXAMIANS APP
