And critically, it needs to be effective at very low doses because even with skin-penetration enhancers, you're rarely getting more than a few milligrams across in 24 hours
Heres what can happen if you inject expired semaglutide: 1
Semaglutide carries an alpha-aminoisobutyric acid substitution at position 8 that blocks that cleavage, plus a C18 fatty-diacid side chain that binds reversibly to circulating albumin
The -propeller domain packs against the / hydrolase domain, and the catalytic triad (residues Ser630, His740 and Asp708) is located at the interface between the two domains (Aertgeerts et al., 2004)
When one of these medications goes off patent, the branded medication shares will decline, because incremental improvements in efficacy or tolerability will not be enough to convince price-sensitive consumers or insurers or healthcare systems to fork over a premium when theres a good enough semaglutide for $60, versus a $6,000 retatrutide
