Chapter 18, Problem 18.61AP

Interpretation Introduction

Interpretation:

Structural formula of dipeptide that contains Aspartate and Leucine is to be identified.

Concept introduction:

Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.

Amino functional group is $(-N{H}_2)$ and carboxyl functional group is $(-COOH)$ and a $R$ group is considered as side chain, when all these are bonded to same carbon atom.

In protein the amide bond ($-CO-NH-$ ) can link together with two amino acids to form a peptide bond.

Link formation results from the release of water.

Formation of peptide bond from between $(-N{H}_2)$ of one amino acid and $(-COOH)$ of another amino acid is called dipeptide bond.
