Homework Answers
The collection of improperly folded protein aggregates are called as amyloid deposits. They are insoluble and form long linear or fibrillar aggregates.
Heat is considered as one of the easiest ways to disrupt or break the hydrophobic bonds present In a protein. At higher temperatures the hydrophobic interactions denature.
Addition of alcohol to a protein helps to disrupt the protein. Alcohol disrupts the Hydrogen bond present between amide groups.

QUESTION 1 To study how proteins fold, scientists must be able to purify the protein of interest, use solvents like urea to denature the folded protein, and observe the process of refolding at successive time points. What is the effect of the solvents used in the denaturation process? a. The solvents break all noncovalent interactions. b. The solvents break all covalent interactions. c. The solvents create a new folded conformation. d. The solvents break some of the noncovalent interactions, resulting...
