Abstract: The action of sodium hypochlorite on some a-amino acids as glycine, serine,,
tyrosine, cystine, aspartic acid, lysine and arginine has been investigated.
It was observed that chlorine reacted very quickly with most of these amino
acids leading to the oxidation and/or formation of chloro derivatives of the
amino acids, depending on the pH of the reaction. At pH 2 and 25°C, oxidation
occurs mainly through the formation of the intermediates iV-chloro
or jV-dichloro derivatives. Substitution of one of the hydrogen atoms of the
amino groups by an acetyl group decreased considerably the rate of oxidation.
A mechanism of the action of sodium hypochlorite on these amino acids
is suggested.
