In peptide synthesis by Boc and Fmoc chemistry, tryptophan can be used without protecting the indole moiety of the sidechain [Boc-Trp-OH, Fmoc-Trp-OH]. The tryptophan residue can be oxidized or can be modified by cationic species during cleavage, most notably the sulfonyl moieties released from arginine moieties.
WebNov 20, 2024 · Tryptophan (Trp) holds a unique place in biology for a multitude of reasons. It is the largest of all twenty amino acids in the translational toolbox. Its side chain is indole, which is aromatic with a binuclear ring structure, whereas those of Phe, Tyr, and His are single-ring aromatics.
