A library of peptide research, organized by hub.
Five subject hubs: peptide science fundamentals, analytical quality, evidence standards, compound profiles by pathway, and regulatory science. Every article separates molecule-level evidence from product-level status.
Fundamentals
Foundational concepts: what peptides are, how they differ from proteins and small molecules, and why precision matters.
Why Peptide Structure Matters: Sequence, Conformation, and Biological Activity
Even a single amino-acid substitution can change receptor affinity, stability, selectivity, or degradation. Peptide structure is not a footnote, it is the foundation of the experiment.
Read articleWhat Makes a Peptide Different From a Protein or Small Molecule?
Peptides occupy a distinct scientific space between traditional small molecules and larger proteins. Understanding that distinction is essential for interpreting research, evaluating material identity, and designing reproducible experiments.
