[β-Asp5]-Desmopressin contains a β-aspartyl linkage at position 5, introducing a backbone isomerization often associated with degradation. The altered geometry affects hydrogen-bond networks and receptor-contact orientation. Researchers use it as a marker for peptide aging and isomerization pathways. Applications include stability studies, impurity profiling, and peptide-backbone rearrangement research.
