Question

What do you call a compound that contains both an amino group and a carboxyl group in the same molecule?

Answer 1

amino acid

An amino acid is a compound that contains both an amino group  NH 2   and a carboxyl group  COOH  in the same molecule. While any number of amino acids can possibly be imagined, biochemists generally reserve the term for a group of 20 amino acids which are formed and used by living organisms. The Figure below shows the general structure of an amino acid.
