(10 pts) A cartoon illustrating a drug binding to the active site of a receptor is shown below. Indicate the types of drug-receptor interactions that appear at each arrow. More than one type of interaction is possible for each letter. Ser Asn OH a H2N Glu O d H3N Val Lys a. d.

Solution

a. Ionic interaction ( Here two opposite charges interact with each other ).

b. Hydrogen bonding interaction ( oxygen of one -OH group form hydrogen bond with hydrogen of another-OH group ).

c. This is hydrophobic interaction.

d. This is the covalent bonding interaction.

e. Weak hydrogen bonding interaction between sulphur and H of NH3 +.
