Chapter 24, Problem 8PS

Interpretation Introduction

Interpretation:

The Lewis structure for the tripeptide $\text{tyrosine-histidine-glycine}$ has to be drawn.

Concept introduction: Amino acids condense to form peptide bonds releasing small water molecules. A peptide bond is the chemical bond which is formed between two molecules of amino acid when carboxyl group of one molecule reacts with the amino group of another molecule. A polypeptide containing $n$ amino acids will have $\left(n-1\right)$ peptide bonds.

The side of a polypeptide chain having free carboxylic group is called C-terminal and the side having free amino group is called N-terminal end.
