Peptide hormones are small, filtered rapidly by the kidney and degraded by circulating enzymes. GLP-1 itself has a half-life of a few minutes. A therapeutic peptide needs to persist far longer, and modifying the peptide to achieve that is a standard problem in peptide drug design.
Albumin binding is one of the established solutions and is used across this class of molecules.
A fatty-acid chain attached to the peptide associates with albumin's fatty-acid binding sites. Bound to albumin, the peptide is too large to be filtered and is shielded from degradation; the binding is reversible, so a fraction is always free to act. The net effect is a half-life measured in days rather than minutes.
The chain length, the linker and the attachment position all influence how tightly the peptide binds and therefore how long it lasts. These were design variables in the discovery work.
Acylation changes the molecule's solubility, its behaviour in solution and its analytical signature. It also means albumin in any experimental system becomes a variable: serum-containing medium will bind the peptide, and the free concentration will differ from the nominal one.
That is a design consideration for any in vitro work with an acylated peptide, and it follows directly from the mechanism that makes the molecule useful.
