Step 1 of 2

Given is the which of the

following interactions could be seen in the tertiary structure of a protein?

1.Gln and Val via a hydrogen bond

2.Pro and Phe via a hydrophobic interaction

3.Asn and Lys via an electrostatic interaction

4.His and Gly via a hydrophobic interaction

5.His and Tyr via an electrostatic interaction.

We found out the which interaction is found in tertiary structure of protein.

Explanation:

We use the concept of biochemistry in which protein tertiary structure is explained.

Step 2 of 2

Here is the Gln=Glutamine, Val=Valine, Pro=Proline, Phe=Phenylalanine, Asn=Asparagine, Lys=Lysine, His=Histidine, Gly=Glycine,

Tyr=Tyrosine.

All formula is given in this table.

As for tertiary structure of protein needs hydrogen bonding, hydrophobic interaction and electrostatic interactions, so these interactions are possible between different kinds of amino acids.

1.As Gln has polar uncharged side chains, but Val has hydrophobic side chain, so they do not interact.

2.As Pro has special case and Phe has hydrophobic side chain so do not interact.

3.As Asn has polar uncharged side chains and Lys has positive charged side chains, so they interact with electrostatic interaction.

4.As His has positive charged side chain but Gly has a special case, so no hydrophobic interaction occurs.

5.As His has positive charge side chain but Tyr has hydrophobic side chains, so electrostatic interaction occurs.

Explanation:

Every detail structure name and formula of all 21 amino acids are given in this table.

So, option 3rd is correct.

Final solution

Option 3 is correct as it fills all criteria for interactions of amino acids.
