Chapter 18, Problem 18.67AP

Interpretation Introduction

Interpretation:

Sequence of atoms along the ‘backbone’ of a protein 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.

Amine 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 can link together with two amino acids to form a peptide bond.

Primary structure of protein is a sequence in which the amino acids linked by peptide bond in a protein.
