SEMAGLUTIDE · DEGRADATION & STABILITY
Semaglutide Degradation & Stability Intelligence
Relevant degradation pathways and stability considerations for semaglutide based on published literature and regulatory data.
Degradation pathway data is based on published literature and regulatory information. Not all pathways necessarily occur under all conditions. PeptiQore does not make stability claims for specific formulations.
DEGRADATION PATHWAYS
Relevant Quality Pathways
Oxidation
Methionine oxidation is a well-characterized degradation pathway for semaglutide and related GLP-1 analogues. Met oxidation products have been reported in forced degradation studies.
Deamidation
Asparagine deamidation under stressed conditions (elevated temperature, pH extremes) is a relevant degradation pathway for semaglutide.
Hydrolysis
Fatty acid side chain hydrolysis (loss of the C18 fatty diacid) is a relevant process and degradation impurity for semaglutide.
Isomerization
Aspartate isomerization (Asp → isoAsp) is a potential degradation pathway under stressed conditions.
Physical Instability
Aggregation-related species have not been prominently reported for semaglutide under standard conditions.
