3
Q
What is a Tertiary Protein Structure?
A
The overall folding pattern or three-dimensional conformation of a polypeptide chain
4
Q
What are the two classes of proteins?
A
- Fibrous
2. Globular
5
Q
What is Quaternary Protein Structure?
A
The overall protein structure that results from the aggregation of two or more polypeptide chains

Q
What bonds are involved in Tertiary and Quaternary protein structures?
A
- Ionic bonds
- Disulfide bonds
- Hydrogen bonds
- Hydrophobic (non-covalent) interactions
