(2R)-2,6-diaminohexanoic acid; (2R,4S)-2-({[(5R)-5-amino-5-carboxypentyl]carbamoyl}(2-phenylacetamido)methyl)-5,5-dimethyl-1,3-thiazolidine-4-carboxylic acid
Benzylpenicilloyl polylysine is poly-L-lysine (n > 40) in which 50-70% of the epsilon-amino groups are substituted with benzylpenicilloyl groups. It is used as a skin-testing reagent to detect immunoglobulin E antibodies in people with a history of penicillin allergy. It has a role as a diagnostic agent. It is a thiazolidinemonocarboxylic acid, a random copolymer, an amino acid amide and a polypeptide. It is functionally related to a benzylpenicillin.
