Interpretation Introduction

Interpretation:

The reason of formation of β-pleated sheets to stack on top of each other in the polypeptide sequence in the regions with amino acid glycine at every other residue needs to be explained.

Concept Introduction:

Proteins are biomolecules which are composed of certain monomer units such as amino acid. These are carboxylic acids with one amino group bonded on alpha-C atom of the molecule. These amino acids involve in condensation process to form peptides and polypeptides which further form complex protein molecules. Amino acids are the organic molecules with both ${\text{–NH}}_{\text{2}}$ and $\text{–COOH}$ groups functional groups bonded on same C atom of the molecule.
