10 Questions
What type of interactions contribute to the tertiary structure of a polypeptide?
All of the above
What is the purpose of hydrophobic interactions in the tertiary structure of a polypeptide?
All of the above
How do disulfide bridges form in a polypeptide?
When two cysteine monomers with sulfhydryl groups on their side chains are brought close together by the folding of the protein
How do turns and loops differ in their contribution to the tertiary structure of a polypeptide?
Turns have well-defined structures, while loops can be formed in many different ways
What is the role of van der Waals interactions in the tertiary structure of a polypeptide?
They help hold together clusters of nonpolar amino acid side chains at the core of the protein
How do hydrogen bonds and ionic bonds contribute to the tertiary structure of a polypeptide?
They help stabilize the overall shape of the protein by interacting between polar and charged side chains
What is the purpose of the hydrophobic core of a protein?
To exclude water molecules and stabilize the overall shape of the protein
How do covalent disulfide bridges contribute to the tertiary structure of a protein?
They further reinforce the shape of the protein by forming additional covalent bonds
What is the overall purpose of the different interactions that contribute to the tertiary structure of a polypeptide?
To exclude water molecules and stabilize the overall shape of the protein
How do turns and loops differ in their contribution to the tertiary structure of a polypeptide?
Loops are more flexible and can be formed in many different ways, while turns have well-defined structures
