Peptide Research Glossary
An educational reference for peptide research terminology. Explore definitions, mechanisms, and scientific concepts used in the field.
A
Amino Acid
Organic molecules that serve as the building blocks of peptides and proteins. There are 20 standard amino acids, each with a unique side chain that determines its properties.
C
Certificate of Analysis (COA)
A document provided by a testing laboratory that confirms the identity, purity, and quality of a compound. COAs typically include HPLC chromatograms, mass spectrometry data, and purity percentages.
H
HPLC
High-Performance Liquid Chromatography. An analytical technique used to separate, identify, and quantify components in a mixture. In peptide research, HPLC is the gold standard for purity verification.
Half-Life
The time required for the concentration of a substance to decrease by half. In peptide research, half-life is an important parameter for understanding compound stability and duration of activity.
L
Lyophilization
A freeze-drying process used to preserve peptides by removing water content. This process maintains peptide stability and extends shelf life while preserving biological activity.
P
Peptide
A short chain of amino acids linked by peptide bonds. Peptides are typically shorter than proteins, generally containing fewer than 50 amino acids. They play crucial roles in biological processes and are widely used in research.
R
Reconstitution
The process of dissolving a lyophilized (freeze-dried) peptide in a suitable solvent, typically bacteriostatic water or sterile water, to prepare it for research use.
Receptor Agonist
A molecule that binds to a receptor and activates it to produce a biological response. Many research peptides function as receptor agonists, mimicking the action of natural hormones or signaling molecules.
