WebTryptophan However, its fluorescent properties are solvent dependent, i.e. the spectrum shifts to shorter wavelengths and increases in intensity as the polarity of the solvent decreases. As such, tryptophan residues buried in hydrophobic domains of folded proteins exhibit a spectral shift of 10 to 20 nm.

WebDec 20, 2024 · For instance, serine exhibits greater polarity than either threonine or tyrosine, because its side chain is shorter and lacks a ring structure and is therefore less non-polar, compared to the other two amino acids. In addition to serine, threonine and tyrosine, asparagine, cysteine, glutamine and tryptophan are both polar and chemically neutral.
WebNov 3, 2006 · The emission spectrum of tryptophan is sensitive to solvent polarity. If the tryptophan residue is buried in a hydrophobic environment within a protein, the emission may be blue-shifted.
