The amino acid responsible for the Hopkins-Cole reaction test is tryptophan. Its formula is C11H12N2O2.
The hopkins-cole test is used to determine the presence of the amino acid tryptophan. Tryptophan has an indole nucleus which is responsible for the violet ring found at the junction between the two layers.
The amino acid responsible for the Hopkins-Cole reaction is the tryptophan because of its indole ring that in the reaction forms a violet color upon treatment of the sample with glyoxylic acid and sulfuric acid.
