The second derivatives of N-acetyl-L-tryptophan amide (AcTrpNH(2)) fluorescence spectra were characterised in order to describe changes in the tryptophan environments of proteins. This tryptophan model compound was studied in several media with different degrees of hydrophobicity. The effect of tyrosines
