Boc-D-His(Trt)-Aib-Gln(Trt)-Gly-OH is a protected tetrapeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the D-histidine (D-His) residue, preventing it from reacting during synthesis. The Trt (Trityl) groups protect the side chains of both histidine and glutamine (Gln), shielding these functional groups until selective deprotection is performed. Aib (α-aminoisobutyric acid), known for inducing helical structures, is the third residue, and Gly (Glycine) is the final amino acid in the sequence, with a free carboxyl group at the C-terminus, indicated by -OH, allowing for further coupling or modifications. This peptide is used to incorporate D-histidine, Aib, and glutamine into peptides, with specific protections to ensure controlled synthesis and functional group reactivity.
