The primary analytical challenges in semaglutide characterization arise from several structural features, including: Acylated lysine residue Fatty acid side chain Spacer/linker chemistry Multiple formulation-associated variants These modifications create substantial analytical heterogeneity that can complicate LC-MS workflows, chromatographic separation, ionization efficiency, and fragmentation analysis

While these atoms serve some beneficial purposes, a free radical imbalance can cause a condition called oxidative stress, resulting in the degradation of proteins, fats, carbohydrates, and DNA
Factors that could delay generics may include: Legal battles: Ongoing patent litigation between the brand-name company and generic manufacturers could delay generic or biosimilar approval even after patents begin to expire
