Draw two amino acid residues interacting through a VDW only

Draw two amino acid residues interacting through (a) VDW only, (b) hydrogen bonded, and (c) making a salt bridge. Label each pair of residues with 3-letter code (or full name). Peptide groups and alpha carbon are optional but NOT needed.

Solution

Hydrogen bond electristatic interaction between negative and positive charges ex. Glutamic acid and lysine form hydrogen bond.

Petplide dond form by N+ and O- ion and show between Glycine and Alanine

Salt bridge form between glutamic acid and arginine.
