Peptides are short chains of amino acids linked by peptide bonds. [1][2] A polypeptide is a longer, continuous, unbranched peptide chain. [3] Polypeptides that have a molecular mass of 10,000 Da or more are called proteins. [4]

Welcome to our website dedicated to peptide chemistry. Developed by professional chemists, our platform is tailored for everyone — from students and professionals to anyone curious about peptides and the fascinating chemistry behind them.

Key Takeaways Peptides, short chains of amino acids, help with blood pressure and wound healing. Some peptide supplements can reduce inflammation and boost muscle growth. Peptides in foods like eggs, milk, and soy may have health benefits, but more research is needed.

Some of the most common peptide supplements available are collagen peptides, which may benefit skin health and reverse the effects of aging.

In organic chemistry, peptide synthesis is the production of peptides, compounds where multiple amino acids are linked via amide bonds, also known as peptide bonds. Peptides are chemically synthesized by the condensation reaction of the carboxyl group of one amino acid to the amino group of another.

Below is a comprehensive peptide list of the most studied and effective compounds, including what they do, how they work, and why they matter for optimal health and longevity.

Peptide, any organic substance of which the molecules are structurally like those of proteins, but smaller. The class of peptides includes many hormones, antibiotics, and other compounds that participate in the metabolic functions of living organisms.

Two or more amino acids linked by peptide bonds form a peptide. Short peptides (2–10 amino acids) are called oligopeptides, while longer chains (10–50 amino acids) are polypeptides.

PeptideAtlas is a multi-organism, publicly accessible compendium of peptides identified in a large set of tandem mass spectrometry proteomics experiments. More... Mass spectrometer output files are collected for human, mouse, yeast, and several other organisms, and searched using the latest search engines and protein sequences.
