The Claim
In rat liver homogenates, the primary initial cleavage site of exendin-4 occurs between Ser11 and Lys12, leading to the formation of exendin-4(12–39) as the main metabolite during in vitro degradation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When scientists break down the drug exendin-4 in a lab dish using rat liver bits, it mostly gets chopped at one specific spot, making a smaller piece called exendin-4(12–39).
See the scientific wording
In rat liver homogenates, the main initial cleavage site for exendin-4 is located between amino acids 11–12 (Ser11-Lys12), resulting in exendin-4(12–39) as the principal metabolite formed during in vitro degradation.
What the research says
1 studyStudy: In Vitro Metabolic Stability of Exendin-4: Pharmacokinetics and Identification of Cleavage Products
The study shows that in rat liver mixtures, exendin-4 is mainly cut right after the 11th amino acid, which matches the claim and leads to the expected fragment.
