Chemotaxonomy

From Wikipedia, the free encyclopedia

Chemotaxonomy (from chemistry and taxonomy), also called chemosystematics, is the attempt to classify organisms (originally plants), according to differences in their biochemical makeup. Mostly the amino acid sequences of proteins are used for comparison. In this approach the taxonomist studies the demonstrable differences and similarities in the biochemical compositions of the organisms to be identified. The compounds studied in most of the cases are Proteins,Amino acids and peptides. John Griffith Vaughan was one of the pioneers of chemotaxonomy.
