Chapter 11, Problem 24Q

Interpretation Introduction

Interpretation:

The way by which the term amino acid suggest its molecular structure has to be given.

Concept introduction:

Amino acids are the molecules containing an amine group, a carboxylic group, and a side-chain that is specific to each amino acid. They are the basic structural building units of protein and other biomolecules.

Carbon, hydrogen, oxygen and nitrogen are the key elements in amino acid.

Some amino acids are listed below,

$\begin{array}{cc}\text{Name}\text{of}\text{amino}\text{acid}& \text{Side}\text{chain}\text{(R)}\\ \text{Glycine}& \text{Hydrogen}\text{atom}\\ \text{Valine}& \text{Isopropyl}\text{group}\\ \text{Leucine}& \text{Isobutyl}\text{group}\\ \text{Cysteine}& {\text{Alcohol(-CH}}_{\text{2}}\text{OH)}\\ \text{Serine}& \text{Thiol}\left({\text{-CH}}_{\text{2}}\text{SH}\right)\\ \text{Phenylalanine}& \text{Aromatic}\text{ring}\left({\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{CH}}_{\text{2}}\right)\end{array}$
