Boc-His(Trt)-Aib-Gln(Trt)-Gly-Gly-OH
Boc-His(Trt)-Aib-Gln(Trt)-Gly-Gly-OH is a protected pentapeptide used in peptide synthesis. It includes histidine (His), α-aminoisobutyric acid (Aib), glutamine (Gln), and two glycine (Gly) residues. The Boc (tert-Butyloxycarbonyl) group protects the N-terminus of the histidine residue, while the Trt (Trityl) groups shield the side chains of histidine and glutamine, preventing premature reactions. The Aib residue adds conformational rigidity, and the two glycine residues at the C-terminus are free, indicated by -OH, allowing for further coupling or modifications. This peptide is designed to ensure controlled reactivity and stability throughout the synthesis process.

Boc-His(Trt)-Aib-Gln(Trt)-OH
Boc-His(Trt)-Aib-Gln(Trt)-OH is a protected tripeptide used in peptide synthesis. The Boc (tert-Butoxycarbonyl) group protects the N-terminus of the histidine (His) residue, preventing it from reacting during synthesis.

Aib (α-aminoisobutyric acid), known for inducing helical structures, is the middle residue. The -OH at the C-terminus of glutamine indicates a free carboxyl group, allowing for further coupling or modifications. This peptide is used to incorporate histidine, Aib, and glutamine into peptides, with specific protections to ensure controlled and efficient peptide synthesis. Synonyms: HXQ; N2-(2-((S)-2-((tert-Butoxycarbonyl)amino)-3-(1-trityl-1H-imidazol-4-yl)propanamido)-2-methylpropanoyl)-N5-trityl-L-glutamine. Grade: ≥95%. Molecular formula: C58H60N6O7.
