Through fatty-acid acylation and amino-acid substitutions, it resists DPP-4 enzymatic degradation and binds albumin, extending its half-life to approximately one week. This engineering classifies Ozempic as a <strong data-start=\"625\" data-end=\"662\">synthetic, lipidated peptide drug<\/strong>, not a small molecule, enabling sustained glucose-dependent insulin secretion and appetite regulation at the receptor signaling level.<\/p>\n<hr data-start=\"799\" data-end=\"802\" \/>\n<h2 data-section-id=\"1ku19qc\" data-start=\"804\" data-end=\"879\"><span class=\"ez-toc-section\" id=\"2_Deep_Mechanistic_Breakdown_From_Phenomenon_to_Molecular_Engineering\"><\/span>2.
