In examining several amino acids, you want to identify the feature or features that differentiate one amino acid from another. what part of the amino acid should you focus on?
a. the amide groups
b. the amino groups
c. the carboxyl groups
d. the hydrogen atoms
e. the side chains

Your answer is C 
amino acids are created by a bond of two carbon atoms and each carbon is part of a different group, one negative and one positive. when the chemical reactions occurs, it creates the several diff amino acids
