(a)

Summary Introduction

To explain: The sign of ΔG for folding and unfolding process of proteins.

Introduction: Proteins are one of the most important parts of the living world. Amino acids combine to form different types of proteins. Proteins can be found in three (or four sometimes) structural forms in nature: primary structure; secondary structure; tertiary structure; and quaternary structure. Tertiary and quaternary structures are the functional structures of proteins. Simpler structures combine and fold in a special manner to form the functional proteins. The unfavorable atmosphere around the proteins can lead to the denaturation of the protein.

Summary Introduction

To explain: Whether the contribution of ΔS to the free energy change will be positive or negative.

Summary Introduction

To explain: The types of bonds needed to be broken for the unfolding of a protein and why extreme heat and pH causes unfolding of the protein.

Reposting - What would the tertiary structure of the dipeptide Asp-Ser be if it was made into a polypeptide chain? (Would it form a beta pleated sheet, an alpha helix, etc) Why would it do this? What properties of this polypeptide causes this? This sub part still needs to be solved - What would the tertiary structure of Pro-ala and Glycl-L-alanine be?
resting state of the protein, the Lys 216 Schiff base has pKa = 9.5 and Asp 85 has pKa = 3.5. When the conformational change occurs, the proton that was on the Schiff base moves to Asp 85. This should tell you that one or both of these two pKas changed with the conformational change. How does the pKa of Asp 85 compare with the pKa of the Lys 216 Schiff base after the conformational change?
