In the context of amino acids, the term "base" refers to the nitrogen-containing group that is part of the amino acid structure. In the case of tryptophan (Trp), the second, or indirect base, is an indole group. It consists of a benzene ring fused to a pyrrole ring, with the nitrogen atom in the pyrrole ring serving as the second base. The indole group is responsible for the unique properties and functions of tryptophan in various biological processes.
