amino acids in this tripeptide. (c) react with ninhydrin to give a blue solution. (Contains the required number of amino acids for reaction.) 27. Hydrolysis breaks the peptide bonds. One water molecule will react with each peptide bond, a hydrogen atom attaches to the nitrogen to complete ...
In this chapter, the term poly(amino acid)s will be used to describe such polymers, as this title reflects that the polymer formed consists of amino acid repeat units, and avoids confusion with peptides that are composed of multiple amino acids arranged in a specific sequence. It is ...
