Speak Peptide

Peptide Glossary.

Peptides come with a lot of jargon. We cut through it. Here’s every term you’ll see on our vials and labels - explained in plain English, so you know exactly what you’re getting and why it matters. No PhD required.

Building blocks

The molecular vocabulary - what a peptide actually is, and the units it's built from.

PeptideA short chain of amino acids.Define →ProteinA large folded amino-acid polymer.Define →Amino AcidThe monomer unit of peptides and proteins.Define →Peptide BondThe covalent amide bond linking amino acids.Define →Amino-Acid SequenceThe ordered list of residues in a peptide.Define →

On the label

Identity & characterization

The descriptors that pin a compound to a single, unambiguous identity in analytical work.

Molecular WeightThe mass of one molecule of a compound.Define →Molecular FormulaThe atom count of a molecule.Define →CAS NumberA unique chemical registry identifier.Define →

In the lab

Handling & form

How a research peptide is supplied, prepared, and kept stable for in-vitro work.

LyophilizedFreeze-dried to a stable solid.Define →ReconstitutionDissolving a lyophilized peptide into solution.Define →Bacteriostatic WaterWater with a preservative for reconstitution.Define →Storage ConditionsHow peptides are kept stable.Define →StabilityResistance to degradation over time.Define →Half-LifeTime for half a compound to clear or degrade.Define →

How they act

Mechanism & receptor language

The signaling terms - how a peptide engages receptors and the systems researchers study.

AgonistA molecule that activates a receptor.Define →SecretagogueA substance that triggers secretion.Define →GHRH AnalogA growth-hormone-releasing-hormone mimic.Define →GHRP (Growth Hormone Releasing Peptide)A ghrelin-receptor agonist peptide.Define →IncretinA gut hormone affecting insulin signaling.Define →Triple AgonistA single molecule activating three receptors.Define →DPP-4 (Dipeptidyl Peptidase-4)An enzyme that cleaves many peptides.Define →DAC (Drug Affinity Complex)A modification that extends half-life.Define →Pituitary SomatotrophThe GH-producing pituitary cell.Define →

Proof, not promises

Quality & compliance

The documentation and framing behind every research-use-only vial.

Certificate of Analysis (COA)A lab document of identity and purity.Define →HPLC PurityPurity measured by chromatography.Define →Research Use Only (RUO)Labeled strictly for laboratory research.Define →
