Interpretation Introduction

Interpretation:

The structure for vasopressin is to be proposed.

Concept introduction:

Vasopressin is a peptide prohormone that regulates the effective osmotic pressure gradient. It comprises $9$ amino acids. Amino acids are carbon containing compounds that possess two functional groups named as amine $\left(-{\text{NH}}_2\right)$ and carboxyl $\left(-\text{COOH}\right)$ and these are prepared by reductive amination of $\alpha -\text{ketoacids}$ by using transaminase enzyme and bromination of carboxylic acid groups followed by amination. Reductive amination comprises transformation of carbonyl group of keto acids to an imine intermediate, which leads to the formation of an amine. Transaminase enzymes are specifically used for speed up the transamination reactions.
