10 Questions
Explain the two shapes that can form within proteins due to the hydrogen bonds mentioned in the text above.
The two shapes that can form within proteins due to the hydrogen bonds are the α-helix and the β-pleated sheet.
What is the specific condition required for the α-helix shape to occur within proteins?
The α-helix shape occurs when the hydrogen bonds form between every fourth peptide bond, specifically between the oxygen of the carboxyl group and the hydrogen of the amine group.
Describe the formation of the β-pleated sheet shape within proteins.
The β-pleated sheet shape forms when the protein folds so that two parts of the polypeptide chain are parallel to each other, enabling hydrogen bonds to form between parallel peptide bonds.
Provide examples of fibrous proteins that have secondary structures.
Collagen and keratin are examples of fibrous proteins that have secondary structures.
What specific interaction does the secondary structure of a protein relate to?
The secondary structure of a protein relates to the hydrogen bonds forming between the amino group and the carboxyl group, which are part of the 'protein backbone'.
What type of bonds form the secondary structure of a protein?
Hydrogen bonds
How does the α-helix shape form within proteins?
When the hydrogen bonds form between every fourth peptide bond
What enables the formation of the β-pleated sheet shape within proteins?
Two parts of the polypeptide chain being parallel to each other
What can break the hydrogen bonds in the secondary structure of a protein?
High temperatures and pH changes
