The building blocks of peptides and proteins, linked together through peptide bonds to form short or long chains used in biological systems and laboratory research.
Browse key peptide and research terms in a clean A–Z format designed for catalogue discovery, education, and laboratory reference.
A
1 termB
1 termPeptides commonly studied for their interaction with receptors, signalling pathways, antimicrobial mechanisms, or immune-related laboratory models.
C
2 termsSmall proteins released by cells that have a specific effect on the interactions and communications between cells, often involved in immune responses.
The semipermeable membrane surrounding the cytoplasm of a cell, which regulates the passage of substances in and out of the cell.
E
2 termsA network of membranous tubules within the cytoplasm of a cell, involved in protein and lipid synthesis.
Proteins that catalyse biochemical reactions in living organisms, often playing critical roles in metabolism and signalling pathways.
G
2 termsAn organelle in cells that modifies, sorts, and packages proteins for secretion or delivery to other organelles.
A class of peptides researched for how they interact with growth hormone signalling pathways under controlled experimental conditions.
L
1 termA molecule that binds to a specific site on a protein, such as a receptor, influencing the function of the protein.
M
2 termsOrganelles found in large numbers in most cells, involved in the production of energy through aerobic respiration.
Peptides that are encoded by mitochondrial DNA or influence mitochondrial function, involved in energy production and apoptosis.
N
2 termsA membrane-bound organelle within eukaryotic cells that contains the genetic material (DNA).
Small protein-like molecules used by neurons to communicate with each other, involved in many physiological signalling pathways studied in neuroscience research.
O
1 termA peptide consisting of a few amino acids, typically between two to twenty.
P
4 termsA long, continuous chain of amino acids. Polypeptides with more than 50 amino acids are typically considered proteins.
Small protein-like chains designed to mimic the biological activity of a natural peptide but with enhanced stability, bioavailability, or specificity.
Chains of amino acids that function as hormones in the body, such as insulin and glucagon, which are involved in metabolic signalling pathways.
A covalent bond formed when the carboxyl group of one amino acid reacts with the amino group of another, releasing water and linking the chain together.
R
2 termsA complex molecular machine found within all living cells that performs the synthesis of proteins according to the sequence of messenger RNA (mRNA).
A protein located on the cell surface or within a cell that binds a ligand and helps initiate or regulate a downstream biological response.
S
3 termsPeptides that are artificially made using peptide synthesis techniques, often designed to mimic or modify the function of natural peptides for research purposes.
A short peptide present at the N-terminus of a protein that directs the protein to specific destinations within or outside the cell.
A peptide hormone that inhibits the release of several other hormones, including growth hormone and insulin, playing a critical role in the endocrine system.
