Peptide Education

What are peptides?

Peptides are short chains of amino acids joined by peptide bonds. They are usually defined as chains of roughly 2 to 50 residues, which separates them from larger, folded proteins. Many peptides occur naturally and act as signalling molecules in the body, for example hormones and neurotransmitters. Research peptides are synthetic versions or analogues of these molecules, made so that scientists can study how they interact with specific receptors and pathways.

How peptides are studied

In laboratory research, a peptide is typically characterised by its amino acid sequence, molecular weight, purity (measured by HPLC) and identity (confirmed by mass spectrometry). Researchers then investigate receptor binding, downstream signalling and effects in cell and animal models. Published findings are listed on each compound page together with PubMed references.

Categories of research compounds

Compounds in our catalogue are grouped by their primary area of scientific interest: metabolic, growth hormone secretagogues, musculoskeletal, neuropeptides, dermal and cellular, mitochondrial and coenzyme compounds, and melanocortin. Many compounds are studied in more than one area, so these groups are a guide rather than a strict classification.

Storage and handling of research materials

Lyophilised (freeze-dried) peptides are generally stored cold, dry and protected from light. Repeated freeze-thaw cycles and humidity can reduce stability, so materials should be kept sealed and allowed to reach room temperature before opening. Always follow the storage guidance in the Certificate of Analysis and on the product page.

Quality and verification

Every batch carries a unique code that can be checked on our Verify Authenticity page. Each product is supplied with a Certificate of Analysis showing purity and identity testing.
