Research Fundamentals

The foundational science of peptides — amino acids, bonds, structure, synthesis and receptor binding. Every serious researcher starts here.

What Are Peptides?

Short chains of amino acids (typically 2–50 residues) linked by peptide bonds. Learn the difference between peptides, proteins and free amino acids.

The 20 canonical amino acids, side-chain chemistry, and how condensation reactions build primary sequence.

Primary, secondary, tertiary structure — and why a single residue swap can abolish receptor binding.

Solid-phase peptide synthesis (SPPS), Fmoc chemistry, cleavage, purification — the whole pipeline that produces a research vial.

Agonists, antagonists, partial agonists, biased signalling. The vocabulary you need to read any peptide mechanism paper.

Molecular weight, sequence notation, salt form, net peptide content — every field on a CoA explained.

Once the fundamentals are solid, move into applied topics: pick a specific compound in the Peptide Guides library, learn how purity is verified in the Quality & HPLC hub, or work through the Reconstitution Academy before touching a vial.
