Chemical Bonds/Interactions found in Proteins?

Question

Can anyone help me? I need to determine the role of each type in determining protein structure. I need three types of chemical bonds/interactions found in proteins.

Answer 1

The three most important are: peptide bonds, hydrogne bonds and dysulfide bonds.

If you recall peptide bonds are the linking between two amino acids through the process of condensation. This is called the primary structure. After that, hydrogen bonds form and the protein folds into either an alpha-helix or beta-pleated. This is called the secondary structure. In the tertiary structure the disulfide bridges form. These are interactions that give the protein its unique shape. Finaly during the quaternary 2 or more proteins come together and form a new one.

Hope it helps

Answer 2

hydrogen bonding look below diagram

Answer 3

Covalent bonds (exclude disulfide bonds) form primary structure - backbone and residues.

Hydrogen bonds inside of protein  - secondary structure.

Hydrogen bonds with solvent - tertiary. Ionic interactions make some impact too.

Hydrophobic interactions - tertiary.

Disulfide bonds don't participate in structure determination (see classic Anfinsen's experiment). DB effects to kinetic stability of folded protein molecules.

Answer 4

hydrogen bonds, hydrophobic interactions, ionic interactions, and/or disulfide bonds.
