WebA favorable cation-Π pair contributes as much to protein stability as a good hydrogen bond or an electrostatic (charge-charge) interaction. Tryptophan is the most frequent π system in protein cation-Π pairs while arginine is the most frequent cation. Tryptophan and arginine can form extended coplaner assemblies. WebTryptophan (Trp) is a heterocyclic, essential amino acid associated with growth, reproduction and immunity. Increased availability of tryptophan is necessary for the regulation of mood, cognition and behavior. The uptake of tryptophan by the brain depends on the plasma ratio of Trp to all of the other large neutral amino acids.
