dc.description.abstractIn this work, the reactions involving L-phenylalanine and D,L-tryptophan in the presence of Cu(II) ion were studied. Optimum conditions for the reactions were established as pH 7 and lambda=641 nm. When the reaction was kinetic, it was observed that the following rate formula was found as dA/A(n) = kdt and k = 3.2 x 10(-4) s(-1), according to absorbance measurements. Using a perpetual change curve, the ratio of [Cu]/[Cu] +L-phenylalanine + [D,L-tryptophan] was found 1:1:1. According to this result, one molecule of L-phenylalanine and one molecule of D,L-tryptophan react with one molecule Cu(II) ion. (C) 2009 Elsevier B.V. All rights reserved.en_US
