11 Questions
What is the structural configuration of the polypeptide chain in an α-helix?
Hydrogen bonding between first and fourth amino acid residues
What is the structural arrangement of a β-sheet?
Accordion-like pleated sheet
Which of the following proteins is an example of a β-sheet structure?
Keratin
What is the cause of Creutzfeldt-Jakob Disease (CJD)?
Prions
What is the effect of prions on the normal prion protein found in the brain?
Prions cause the normal prion protein to misfold into a β-pleated sheet structure
What is the name given to the simplest level of structural organization in proteins?
Primary structure
What happens to the migration of a protein in an electric field when it is at its isoelectric point?
The protein does not migrate since its net charge is 0
Which of the following is NOT a type of secondary structure found in proteins?
Quaternary structure
What is the role of chaperone proteins in protein folding?
They assist in the folding and unfolding of the polypeptide to correctly form the tertiary structure
Which type of bond contributes to the stabilization of the tertiary structure of a protein?
All of the above
What is the main cause of Creutzfeldt-Jakob Disease (CJD)?
Both (b) and (c)
Explore the structures of α-helix and β-sheets in proteins, as well as diseases like Creutzfeldt-Jakob caused by protein misfolding. Learn about the hydrogen bonding patterns that form the α-helix and the accordion-like structure of β-sheets.
