Peptides are usually grouped by function. The main families are hormonal peptides, neuropeptides, structural peptides, carrier (copper) peptides, and antimicrobial peptides. In the research market, peptides are also grouped by the pathway or system they interact with.
Grouped by function
| Type | What it does | Example |
|---|---|---|
| Hormonal | Regulates a body process as a signal | Insulin, glucagon |
| Neuropeptide | Signals within the nervous system | Endorphins |
| Structural | Fragments tied to tissue and structure | Collagen peptides |
| Carrier / copper | Binds and carries other molecules | GHK-Cu |
| Antimicrobial | Part of natural defense systems | Defensins |

How research peptides are grouped
Catalogs of research peptides tend to organize compounds by the area of study they relate to, for example metabolic research, recovery and repair research, or cosmetic and skin research. This is why you will see a peptide like GHK-Cu described as a copper peptide, while others are grouped by the pathway they act on. You can see these groupings across the Axis catalog.
Key takeaways
- Peptides are commonly grouped by function.
- Main families: hormonal, neuropeptide, structural, carrier/copper, antimicrobial.
- Research peptides are often grouped by the pathway or system they act on.
- The same peptide can be described more than one way depending on context.
A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
