HOPKINS AND THE DISCOVERY OF TRYPTOPHAN
Hopkins and Cole, first isolated tryptophan from protein digests at Cambridge at the beginning of this Century. It is therefore appropriate for the proceedings volume of the first British meeting of ISTRY to contain an article on Hopkins and his work. Hopkins, the principal founder of modern biochemistry in the UK, was born in Eastbourne in 1861.

An amino acid is a molecule that contains an amino group and a carboxyl group in the same molecule. Amino acids found in proteins are α-amino acids. This means the amino group (NH 2 - or NH 3+ -) is attached to the alpha carbon--this is the carbon next to the carboxyl group. There are 20 amino acids that differ from each other only in the ...

Adamkiewicz–Hopkins' test
Adamkiewicz–Hopkins' test (Hopkin's-cole test) This test used for detecting the presence of tryptophan in proteins. Principle: The compounds that have indole ring can condense with aldehydes (more readily with formic aldehyde) to form colorful condensation products. Among protein amino acids, only tryptophan undergoes this reaction.
