PL.5 Flashcards
Protein structure and the bonds that determine the different levels of structure
1
Q
What are the three levels of protein structure?
A
Primary, secondary, and tertiary structures.
2
Q
What is the primary structure of proteins?
A
The order amino acid residues are arranged in.
3
Q
What is the secondary structure of proteins?
A
The coiling and folding of the chain of amino acids as a results of hydrogen bonding.
4
Q
What is the tertiary structure of proteins?
A
The folding of the secondary structure to give rise to the protein’s overall 3D shape.
5
Q
What are the two types of secondary structure?
A
Helices and sheets.
6
Q
What types of bonds hold the tertiary structure together?
A
Intermolecular bonds, ionic bonds, and covalent bonds between side chains.
