What determines the primary structure of a protein, and how does it influence the subsequent structures?
What determines the primary structure of a protein, and how does it influence the subsequent structures?
The primary structure of a protein is determined by the inherited genetic information, and it determines the secondary and tertiary structures of a protein.
What type of bonding is responsible for stabilizing the secondary structure regions of a protein?
What type of bonding is responsible for stabilizing the secondary structure regions of a protein?
Hydrogen bonds between atoms of the polypeptide backbone
What is the characteristic feature of an α-helix, and how does it differ from a β-pleated sheet?
What is the characteristic feature of an α-helix, and how does it differ from a β-pleated sheet?
An α-helix is a delicate coil held together by hydrogen bonding between every 4th amino acid, whereas a β-pleated sheet is a structure in which two or more strands of polypeptide chains lay side by side connected by hydrogen bonding.
What is the functional significance of the β-pleated sheets in the spider silk protein, and how does it relate to the spider's web?

What type of interactions are responsible for positioning hydrophobic amino acids in the core of a protein, and what is the resulting effect on the tertiary structure?
How do disulfide bridges contribute to the stabilization of a protein's tertiary structure, and what amino acids are involved in this process?
How do disulfide bridges contribute to the stabilization of a protein's tertiary structure, and what amino acids are involved in this process?
What is the role of hydrogen bonds in stabilizing both secondary and tertiary structures of a protein, and how do they differ in their interactions?
