What Are Peptides?

An introduction to peptides — short chains of amino acids that serve as the building blocks of more complex biological molecules and signaling agents.

Peptides vs. Proteins

What distinguishes a peptide from a protein? Explore the differences in chain length, folding, function, and laboratory handling.

How Peptides Interact With Receptors

Peptides exert their biological effects by binding cell-surface receptors. Learn about binding affinity, selectivity, and signal transduction.

Understanding Peptide Structure

From primary sequence to secondary and tertiary folding — a detailed look at the structural levels that define peptide behavior.

What Is Peptide Stability?

Temperature, pH, enzymatic degradation, and oxidation all affect how long a peptide remains intact. Learn what drives degradation and how to minimize it.

How Peptides Are Synthesized

Solid-phase peptide synthesis (SPPS) is the industry standard. Explore the step-by-step chemistry behind building peptide chains in the laboratory.

What Is Lyophilization?

Freeze-drying is the gold standard for preserving peptides. Understand the physics of sublimation and why lyophilized peptides ship and store better.

Understanding Peptide Solubility

Not all peptides dissolve the same way. Learn how amino acid composition, charge, and solvent choice affect reconstitution in the laboratory.
