Describe primary, secondary, tertiary, and quaternary structure and differentiate among the structures based on
Solution
Quaternary Structure of Proteins- are stabilized by hydrophobic interaction, hydrogen bonding
Many proteins are formed from more than one polypeptide chain. The quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits. |
Tertiary Structure of Proteins- are stabilized by salt bridges, disulphide bonds.
Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape. |
