15 Questions
Which of the following determines the folding of a single strand of protein into a 3D structure?
Formation of hydrogen bonds
What is the role of chaperones in protein folding?
They assist with folding
What are the two phenomena that assist in stabilizing the protein during folding?
Formation of hydrogen bonds and reduction of surface area
What induces compact folding of proteins by internalizing hydrophobic amino acids?
Hydrophobic effect
Which structures fold first during protein folding?
Secondary structures
Which of the following is true about protein folding in dilute solution?
Proteins can fold without the assistance of chaperones.
What is the role of hydrogen bonding in protein folding?
Hydrogen bonding reduces strain in the protein backbone.
What is the hydrophobic effect in protein folding?
It is the internalization of hydrophobic amino acids from the aqueous solution.
What is the most stable conformation of a protein?
The tertiary structure.
Can proteins fold reversibly?
Yes, proteins can fold reversibly.
What are some trends in protein folding?
Secondary structures fold first. Nonpolar residues aggregate or form a hydrophobic collapse.
How are proteins able to fold without chaperones?
In dilute solution, proteins can be folded without chaperones.
What are the two phenomena that assist in stabilizing the protein during folding?
Formation of lots of hydrogen bonds and reduction of surface area accessible to the aqueous solvent.
What role does the hydrophobic effect play in protein folding?
The hydrophobic effect induces compact folding of proteins by internalizing hydrophobic amino acids from the aqueous solution.
Are proteins able to fold reversibly?
Yes, proteins can fold reversibly.
