Abstract
IN connexion with some projected immuno-chemical work, we have recently had occasion to synthesize cysteyl- and cystyl-tyrosine and tyrosyl-cysteine and -cystine. Since these peptides represent a type which has not hitherto been available, it was considered worth while to study the action on them and their N-carbobenzyloxy derivatives of crystalline pepsin.
