Chapter 21, Problem 21.101CP

Interpretation Introduction

Interpretation:

The reason for aspartic and glutamic amino acids to have $+1$ a net charge at low pH but at high pH, the net charge is to be explained.

Concept introduction:

Amino acids are organic compounds containing two functional groups namely amino and carboxylic group. Amino group is attached to the alpha carbon, carbon adjacent to the carbonyl group making them alpha-amino acids.

There are $20$ amino acid that occurs naturally depending only in the difference of R group bonded to the alpha carbon. The group R is called the side chain of the amino acid.
