Common Terms & Definitions
Use this glossary to quickly find clear, easy-to-understand definitions of key terms used in peptide research and laboratory science.
Amino AcidThe building blocks of proteins. Peptides are short chains of amino acids.
There are 20 standard amino acids. The order in which they are linked (the sequence) determines a peptide’s structure and how it behaves in a research setting.
BioavailabilityRefers to how much of a substance is available to interact in a biological system in research settings.
Bioavailability is usually expressed as a percentage and can be influenced by factors such as stability, solubility and the research model being used.
Half-LifeThe amount of time it takes for half of a substance to be eliminated or no longer detectable in a system.
Half-life is commonly reported in research literature to describe how long a compound remains measurable. Values can differ significantly between peptides and study conditions.
LyophilizationA freeze-drying process used to remove water from a product to improve stability and shelf life.
Most research peptides are supplied as a lyophilized (dry) powder or cake inside a sealed vial, which helps protect them during shipping and storage.
PeptideA short chain of amino acids that is studied for various research applications in laboratory and scientific settings.
Peptides are generally defined as chains of roughly 2 to 50 amino acids. Longer chains are typically classified as proteins.
PurityThe percentage of the desired peptide in a product, often verified through laboratory testing.
Purity is commonly measured using HPLC (high-performance liquid chromatography), often alongside mass spectrometry to confirm the peptide’s identity.
ReconstitutionThe process of adding a specific liquid (such as bacteriostatic water) to a lyophilized peptide to make it usable for research.
Reconstitution should always follow the instructions supplied with the specific product. Once reconstituted, a peptide’s storage requirements and stability can change.
Research Use OnlyIndicates that a product is intended strictly for laboratory and scientific research, not for human consumption.
All Alpha Strong Peptides products are sold for research use only. They are not intended to diagnose, treat, cure or prevent any condition, and are not for human or animal use.
StabilityThe ability of a peptide to maintain its integrity and effectiveness under recommended storage conditions.
Heat, light, moisture and repeated temperature changes are common factors that can reduce stability over time.
StorageProper handling and storage conditions help maintain the quality and stability of research peptides.
See our Storage Instructions page for general guidelines, and always follow the storage information supplied with each product.
