Tryptophan color
WebThe Effect of Tryptophan and Tyrosine in Protein Quantitation. Due to the presence of tyrosine and tryptophan, proteins and peptides containing these aromatic amino acids absorb UV light at a wavelength of 280 nm. Each of these residues has distinct absorption and emission wavelengths and varies in quantum yields. WebThe absorbance of ultraviolet light by tryptophan is greatest, that of tyrosine is less, and that of phenylalanine is least. If the tyrosine or tryptophan content of the protein is known, therefore, the concentration of the protein solution can be determined by measuring its absorbance between 280 and 290 nanometres.
