Three residues & cellular transport
Three residues make a compact research peptide, but its literature still depends on the model and the transport system being studied. This article follows one original study and separates uptake from other outcomes.
01
A study centered on cellular transport
A Gastroenterology paper published online in 2007 and in the 2008 journal volume investigated a Lys–Pro–Val tripeptide and the PepT1 transport system. The work included cell models and animal experiments.
The two publication dates reflect online and issue publication, not two separate discoveries. Recording the actual paper identifier helps avoid counting the same evidence twice.

02
Transport is a specific research question
A transport experiment asks whether and how material moves through a biological system under defined conditions. Its model, comparison group and analytical method are essential to the finding.
Do not collapse uptake, molecular signaling and a whole-organism endpoint into one claim. A paper can investigate several of these questions, but each requires its own experimental evidence.

03
Single-component material versus a blend
The reference sequence has three residues. The standalone catalog entry and a multicomponent blend containing that sequence are different supplied materials. A study on the isolated tripeptide is related background for a blend, not a direct experiment on that blend.
Check the exact formulation and the amount attributable to each component. A total blend amount cannot be read as the amount of every ingredient.
A little more clarity
Questions, answered
Are the 2007 and 2008 dates contradictory?
No. This paper appeared online before its journal issue. Use the source identifier to recognize the same publication.
Does a blend’s total amount tell me the amount of this component?
No. Read the component breakdown or obtain it from the supplier.
Follow the evidence
