Chapter 8, Problem 142QP

The proteins in our bodies are built from small organic molecules called acids. An amino acid is a class of organic compound that contains both an amine functional group and a carboxylic acid functional group. Draw the Lewis structure for an amino acid that has one $-{\text{CH}}_{\text{2}}-$ sandwiched between $-{\text{NH}}_{\text{2}}\text{and}-{\text{CO}}_{\text{2}}\text{H}\text{groups}\text{.}$
