Stereochemical Variants
Defined D-amino-acid or other stereochemical variants at specified sequence positions.
A library of 124 listed Tirzepatide-related research peptides for HPLC and LC-MS comparison, analytical method development, stability investigations and related-substance studies.
LifeTein provides custom synthesis of Tirzepatide impurity peptides for research involving chromatographic separation, mass-spectrometry comparison, stability-indicating method development, process-related variants and candidate degradation products.
Tirzepatide contains a modified peptide backbone and a fatty-acid-containing side chain. The library includes specified stereochemical, sequence-related and chemically modified research variants.
Defined D-amino-acid or other stereochemical variants at specified sequence positions.
Substitution, deletion and truncation peptides related to the parent sequence.
Asp-related rearrangements, oxidation products and linker- or lipidation-related variants where listed.
