semaglutide vs tirzepatide vs retatrutide Compared Retatrutide vs Tirzepatide vs Semaglutide

Three modifications work in combination Aib8 substitution eliminates DPP-IV cleavage at position 8, Arg34Lys substitution removes a proteolytic cleavage site, and the C18 fatty diacid conjugated via a hydrophilic mini-PEG linker at Lys26 enables tight reversible albumin binding that shields Semaglutide from proteolytic degradation and renal clearance, producing the approximately one-week half-life through albumins own pharmacokinetics

The dominant precursor ion is [M+4H]4+ at m/z 1029.3 , with [M+5H]5+ also observed
