Tryptophan side chain pka
WebBased on this, it was proposed that SCN − and GdnH + ions can bind to side chains of hydrophobic and, in particular, aromatic amino acids of the protein . In the case of GdnH + ions, this assumption was also supported by the observation that in proteins the guanidinium group of the arginine residue is often located almost parallel to the aromatic … WebAug 9, 2024 · Viewed 19k times. 1. Since Tyrosine and Tryptophan are amino acids, their polarity is determined on their side chains or R groups. If their R groups are polar, the amino acid is polar. Both Tyrosine and Tryptophan are listed as non-polar molecules. However, Tryptophan has nitrogen in its side chain and Tyrosine has oxygen, both of which have a ...
