Peptide Handbook - A Guide to Peptide Design and Applications in Biomedical Research - First Edition

Oct 13, 2026

Peptide Handbook provides a structured guide to peptide design and biomedical applications, starting with fundamental concepts of peptide structure, including peptide bond formation, N- and C-terminal residues, backbone carbon naming, and amino-acid chirality. It explains how molecular features such as pI and ionization behavior arise from amino-acid composition. The handbook then maps core analytical methods and broad application areas, spanning structural biology, disease pathogenesis, antibody generation, vaccine development, immunotherapy, cell penetration, and regenerative medicine.

The formation of the covalent peptide bond is an example of a condensation reaction, which generates water from the combination of the α-carboxyl group of one AA and the α-amino group of another. An AA unit within a peptide chain is called a "residue”. A peptide can be as short as two residues with only one peptide bond (named “dipeptide”) or as long as several residues forming a continuous and unbranched peptide chain (named “oligopeptide” if containing <20 AAs or polypeptide if containing >20 AAs) . Proteins are comprised of many peptide chains and sometimes the terms “polypeptide” and“protein” are used interchangeably. There are several diﬀerent conventions for making a distinction between the two, but in general, molecules referred to as polypeptides have molecular weights (MWs) below 10,000 Daltons or less than 50 AAs, and molecules above these limits are considered as proteins (Lehninger et al.)

FAQs

What does a peptide consist of according to the handbook?

A peptide is described as a chain of amino acids linked by amide or peptide bonds (covalent peptide bonds).

How are peptide termini and backbone features defined?

The handbook defines the end with a free α-amino group as the N-terminal residue and the end with a free carboxyl group as the C-terminal residue, and it names the backbone carbon as the α carbon (Cα).

Which biomedical research areas are covered under peptide applications?

The table of contents lists applications including structural biology, disease pathogenesis, antibody generation, vaccine development, drug discovery and development, immunotherapy, cell penetration-based applications, tissue engineering and regenerative medicine, cosmetics, and food industry.
