L-Phenylalanine b-naphthylamide
CAS :L-Phenylalanine b-naphthylamide is a phenylalanine derivative that can be used as an indicator for the detection of Clostridium, 2-naphthylamine, and other anaerobes. This compound is a chromogenic substrate that reacts with amino groups in amino acids and amides in peptides to form a variety of color products. The condensation of phenylalanine with 2-naphthylamine is catalyzed by enzymes found in clostridia. When L-phenylalanine b-naphthylamide is incubated with tissue from animals or humans, it produces a pink coloration that indicates the presence of clostridia. The aerobic conditions necessary for this reaction are also found in the environment and within the body.Formule :C19H18N2ODegré de pureté :Min. 95%Masse moléculaire :290.36 g/molN-(Aminocarbonyl)aspartic acid
