説明

The oxidation kinetics of cysteine by potassium ferricyanide (F) in aqueous solution has been studied in the pH range of 1.90-2.26 at 32.0℃. The two compounds react in equimolar ratio and in excess of cysteine; the rate law-d[F]/dt=k[F]^2 was found to be app1ied. The order in cysteine is two. The observed rate constant (k) was found to increase with increasing pH, to decrease with increasing initial ferricyanide ion concentration and with added small concentration of ferrocyanide, and to be unaffected by added cystine and the salts. These results are discussed in terms of a mechanism in which an initial reversible electron transfer is followed by another irreversible reactions.
