H-Gln(Trt)-Gly-OH
H-Gln(Trt)-Gly-OH is a dipeptide used in peptide synthesis. The H indicates a free N-terminus, meaning there is no protective group on the amino group of the first amino acid, Gln (Glutamine). The side chain of glutamine is protected by a Trt (Trityl) group, which prevents the side chain amide from participating in unwanted reactions during synthesis. Gly (Glycine) is the second amino acid in the sequence, known for its small and flexible nature. The -OH at the C-terminus indicates a free carboxyl group, allowing the dipeptide to be further extended in peptide synthesis. This compound is used to incorporate glutamine and glycine into peptides, with specific protections in place to ensure selective reactions. Synonyms: N5-Trityl-L-glutaminylglycine; QG. Grade: ≥95%.

H-Glu(OtBu)-Glu(OtBu)-Tyr(OtBu)-Leu-OMe is a protected tetrapeptide used in peptide synthesis. The sequence contains two glutamic acid (Glu) residues, a tyrosine (Tyr) residue, and a leucine (Leu) residue. The side chains of the glutamic acid and tyrosine residues are protected by OtBu (tert-butyl) groups, preventing their carboxyl and hydroxyl groups from reacting prematurely during the synthesis process. The N-terminus of the first glutamic acid is free, indicated by H-, and the C-terminus of the leucine residue is esterified as OMe (methyl ester), which can be used for further chemical modifications or as a temporary protection for the carboxyl group. This protected tetrapeptide is designed to facilitate the controlled and efficient incorporation of these amino acids into peptide chains. Synonyms: EEYL; tert-Butyl (S)-4-amino-5-(((4S,7S,10S)-7-(4-(tert-butoxy)benzyl)-4-isobutyl-15,15-dimethyl-3,6,9,13-tetraoxo-2,14-dioxa-5,8-diazahexadecan-10-yl)amino)-5-oxopentanoate; L-α-Glutamyl-L-α-glutamyl-O-(1,1-dimethylethyl)-L-tyrosyl-L-leucine 1,2-bis(1,1-dimethylethyl) 4-methyl ester; L-Leucine, L-α-glutamyl-L-α-glutamyl-O-(1,1-dimethylethyl)-L-tyrosyl-, 1,2-bis(1,1-dimethylethyl) 4-methyl ester.

H-Glu(OtBu)-Ile-Pro-OMe
H-Glu(OtBu)-Ile-Pro-OMe is a protected tripeptide used in peptide synthesis. The H indicates a free N-terminus on the glutamic acid (Glu) residue, which is protected on its side chain by an OtBu (tert-butyl) group, preventing the carboxyl group from reacting during synthesis. Ile (Isoleucine) is the middle amino acid, contributing hydrophobic properties, while Pro (Proline), the last amino acid, is known for its ability to induce turns or kinks in peptide chains due to its rigid structure. The OMe (methyl ester) at the C-terminus means the carboxyl group of proline is esterified, which can be advantageous for further chemical modifications or to prevent unwanted reactions during peptide elongation. This tripeptide is used to introduce glutamic acid, isoleucine, and proline into peptides, with selective protection to ensure controlled reactivity throughout the synthesis process. Synonyms: EIP; Methyl ((S)-2-amino-5-(tert-butoxy)-5-oxopentanoyl)-L-isoleucyl-L-prolinate. Grade: ≥95%. Molecular formula: C21H37N3O6. Mole weight: 427.54.
