Webreach the detector, (4) it causes the observed emission spectrum to be red-shifted because it asymmetrically affects tryptophan’s excitation band (Ladokhin et al., 2000). These problems are demonstrated in Fig. 6.2. We dissolved one sample of L-tryptophan zwitterion into a blank buffer solution and a second sample WebFeb 1, 2024 · The spectrum of tryptophan also exhibits a Fermi resonance doublet, with lines at approximately 1360–1340 cm-1. When the relative intensity is greater than 1.1, the sidegroup is sitting in a hydrophobic environment, but when it is less than 0.9, it is in a hydrophilic environment.

WebAs such, tryptophan residues buried in hydrophobic domains of folded proteins exhibit a spectral shift of 10 to 20 nm. Due to its greater absorptivity, higher quantum yield, and resonance energy transfer, the fluorescence spectrum of a protein containing the three amino acids usually resembles that of tryptophan. Tyrosine Webbe observed in the absence of both tryptophan and tyrosine. Due to tryptophan’s greater absorptivity, higher quantum yield, and resonance energy transfer, the fluorescence … WebOther names: Tryptophan, L-; L-α-amino-3-indolepropionic acid; Tryptophan; L-Tryptophane; α-Aminoindole-3-propionic acid; ...
