Chapter 23, Problem 23QAP

Interpretation Introduction

Interpretation:

The two amino acids arginine and serine can combine to from a dipeptide. The structure of two possible dipeptides formed from these two amino acids needs to be drawn.

Concept introduction:

Amino acids are organic compounds containing amino as well as acidic groups. The general molecular formula of an amino acid is as follows:

${\text{H}}_{\text{2}}\text{N-CH}\left(R\right)-\text{COOH}$

Here, R refers to different group for different amino acids. If there is more than one amino group present in an amino acid, they are considered as basic amino acids and if there is more than one carboxylic group then they are considered as acidic amino acids.

Amino acids are the simplest unit of a peptide chain. These amino acids are linked through peptide bonds and results in the formation of protein.
