The definitive A-Z compendium of peptide biochemistry, cellular organelles, and molecular research leads. This index provides the technical vocabulary required for high-fidelity laboratory investigation and the study of biochemical signalling pathways.

STRICTLY FOR SCIENTIFIC RESEARCH: Amino Peptides Ltd is a research-only supplier. Products are intended strictly for in-vitro laboratory research and development (R&D). Not for human, diagnostic, therapeutic, or veterinary use.
A — C
Acetic Acid An organic solvent used in research to facilitate the dissolution of hydrophobic peptides. Sequences may require 10% acetic acid to prevent precipitation in aqueous buffers.
Adipotide (FTPP) A peptidomimetic pro-apoptotic agent. Research focuses on its targeted signalling in adipose tissue vasculature via the Prohibitin receptor pathway.
Amino Acids The fundamental monomers of peptides and proteins, characterised by an amino group (-NH2), a carboxyl group (-COOH), and a variable side chain (R group) that dictates chemical properties.
Bacteriostatic Water Sterile water containing 0.9% benzyl alcohol. Used in research to prevent bacterial growth and maintain the stability of reconstituted peptide sequences.
Bioactive Peptides Sequences that elicit a measurable biological signal within a cell culture or test model. Investigated for immunomodulatory, antimicrobial, and signalling-specific activities.
BPC-157 A stable gastric pentadecapeptide. Notable for its resistance to enzymatic hydrolysis and its scrutiny in studies regarding the VEGF (Vascular Endothelial Growth Factor) pathway.
Cell Membrane The phospholipid bilayer that serves as a semi-permeable boundary, regulating the flux of ligands and reagents into the cytoplasm.
Certificate of Analysis (COA) A Certificate of Analysis (COA) is an official laboratory document proving a specific batch meets strict quality, purity, and identity standards. For research peptides, it guarantees the vial matches the label exactly, free from synthesis by-products or degradation bridging manufacturing rigor with your research integrity.

D — G
Endoplasmic Reticulum (ER) An organelle network involved in protein folding and lipid synthesis. Research often examines how specific peptides influence "ER stress" pathways.
Enzymes Biological catalysts that facilitate biochemical reactions. Peptide research often investigates how certain sequences act as enzyme inhibitors or substrates.
Epitalon A synthetic tetrapeptide (Ala-Glu-Asp-Gly). Research focuses on its role in telomerase activation and cellular senescence assays.
Golgi Apparatus The cellular organelle responsible for modifying, sorting, and packaging proteins. Investigated in studies of protein secretion and intracellular trafficking.
GHRP (Growth Hormone-Releasing Peptides) A class of synthetic peptides (e.g., GHRP-2, GHRP-6) that act as ghrelin receptor mimetics to investigate pulsatile somatotropic signalling.
H — M
HPLC (High-Performance Liquid Chromatography) The gold-standard analytical technique for determining chemical purity. Amino Peptides Ltd standards require >98% area purity for all reagents via HPLC and LC-MS (Mass Spectrometry).
Ligand A molecule that binds to a specific receptor site to trigger a biological response. Peptides serve as high-affinity ligands in many signalling assays.
Lyophilisation A sublimation-based dehydration process. This ensures the structural integrity of peptide bonds and allows for stable, room-temperature transit.
Mass Spectrometry (LC-MS) An analytical method used to verify the molecular weight and sequence identity of a peptide, ensuring the compound matches its intended chemical fingerprint.
Mitochondria The organelles responsible for ATP production via aerobic respiration. A primary focus in research involving mitochondrial-derived peptides (MDPs).
Mitochondrial Peptides Sequences encoded by mitochondrial DNA (like MOTS-c) scrutinised for their influence on energy metabolism and cellular apoptosis.
N — Q
Neuropeptides Protein-like signalling molecules utilised in neuronal communication. Research models examine their influence on neurotransmission and physiological homeostasis.
Net Peptide Content (NPC) The weight percentage of a vial that is actual peptide, excluding moisture and counter-ions (TFA/Acetate). Vital for precise molarity math.
Nucleus The membrane-bound organelle containing the cell's genetic material. Many peptides are researched for their ability to influence nuclear transcription factors.
Oligopeptide A peptide consisting of a short chain of amino acids, typically between two and twenty residues.
R — S
Receptor Specialised proteins that recognise specific ligands. Peptide research typically focuses on receptor-ligand affinity and downstream signal transduction.
Ribosome The molecular machine responsible for protein synthesis (translation). Research often focuses on how peptides might influence or bypass ribosomal pathways.
Somatostatin A peptide hormone that serves as a universal inhibitor of several signalling pathways, including growth hormone and insulin-related axes.
Signal Peptide A short amino acid sequence (usually at the N-terminus) that directs a protein to a specific cellular destination or for secretion.
Synthetic Peptides Reagents produced via Solid Phase Peptide Synthesis (SPPS) designed to mimic or modify natural sequences for laboratory investigation.
T — Z
Peptide Bond The covalent chemical bond formed between the carboxyl group of one amino acid and the amino group of another, involving the release of H2O.
Peptide Hormones Amino acid chains that serve as systemic signalling molecules, such as insulin, investigated for their role in metabolic homeostasis.
Peptidomimetics Small molecules designed to mimic the biological activity of a peptide while offering enhanced stability and resistance to enzymatic cleavage.
Polypeptide A continuous chain of amino acids. Sequences exceeding 50 residues are traditionally classified as proteins.
TB-500 A synthetic fragment of the Tβ4 molecule. Research centres on its actin-sequestering properties and role in promoting endothelial migration.

Storage & Stability Protocols

To ensure the structural integrity of >98% purity research analytes, the following protocols must be observed:

  • Lyophilised Storage: Short-term (daily/weekly) at 2°C to 8°C. Long-term (months/years) at -20°C or -80°C. Keep vials protected from UV light.
  • Reconstitution Protocol: Allow vials to reach room temperature (15–20 mins) before opening. Use the "Wall Method"—aiming the solvent at the inside wall of the vial to let the liquid slide down slowly.
  • Post-Reconstitution Care: Liquid peptides must be refrigerated at 2°C to 8°C. Most sequences remain stable for 2 to 4 weeks. Do not refreeze after reconstitution, as ice crystals can damage delicate peptide bonds.
  • Mechanical Stability: Avoid vigorous shaking or agitation, which can cause "shearing" and denature the protein chains. Gently swirl until the solution is clear.
