Acetyl Hexapeptide-37
Also known as —
An acetylated hexapeptide investigated in epidermal models for aquaporin-3 expression and membrane-transport biology.
- Length
- 6 amino acids
- Half-life
- Not well characterised
- Mechanism
- Ingredient-development studies describe increased aquaporin-3 expression in epidermal cell models. Aquaporin-3 is a membrane channel rather than a receptor, and direct binding or channel gating by the peptide has not been established.
- Studied in
- Keratinocyte cultures and reconstructed epidermal models investigate aquaporin-3 expression, localisation and associated water- or glycerol-transport endpoints.
About Acetyl Hexapeptide-37
Acetyl Hexapeptide-37 is a synthetic six-residue peptide associated with aquaporin-focused cosmetic research. Its complete sequence, stereochemistry and terminal chemistry should be confirmed from supplier documentation before experimental comparison. Aquaporin-3, the principal protein discussed in this research context, is an aquaglyceroporin that conducts water and glycerol across cell membranes. The peptide is not itself a channel, and its ingredient designation does not establish a natural sequence origin or receptor-binding motif.
The reported research rationale concerns modulation of aquaporin-3 abundance in epidermal cells rather than a demonstrated interaction with a defined receptor. Transcript measurements, protein quantification and membrane localisation address different parts of that hypothesis and should not be treated as interchangeable. Transport assays provide a separate functional test. For research use only, findings from ingredient-development models require careful controls and independent replication before a specific upstream signalling mechanism can be assigned.
Laboratory notes
- Confirm sequence and terminal modifications on the batch certificate; residue count alone is insufficient to establish identity.
- Measure AQP3 transcript and protein separately, using validated antibodies and appropriate normalisation for cell number or total protein.
- For transport assays, control osmotic gradients, membrane integrity and cell viability; increased protein abundance does not necessarily indicate increased functional transport.

Questions about Acetyl Hexapeptide-37
Is aquaporin-3 a receptor for this peptide?
No receptor relationship has been established. Aquaporin-3 is a membrane transport channel, and expression changes do not demonstrate direct peptide binding.
What distinguishes AQP3 from a water-only aquaporin?
AQP3 belongs to the aquaglyceroporin subgroup and permits glycerol as well as water transport. Functional experiments should specify which transported substance is being measured.
Does higher AQP3 messenger RNA establish increased transport?
No. Translation, membrane localisation and channel function must also be considered. Protein measurements and a separate transport assay are needed to evaluate that connection.
Is Acetyl Hexapeptide-37 for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or animal consumption.
