Abstract
Conjugation of p-nitrobenzoic acid, p-amino-benzoic acid and [14c]benzoic acid has been studied in representatives of 3 arachnid Orders. N2-Aroylarginines were formed in each species. In Boophilus, Tegenaria, Agelena and Epeira aroylglutamic acids were also found. In Tegenaria, Epeira, Agelena, Mitopus and Phalangium, N2-aroylglutamines were found.
