Peptides sit at the intersection of chemistry, biology, and modern biotechnology. Their modular structure, tunable properties, and diverse biological roles make them essential tools across research and scientific innovation. This handbook acts as your central hub—a structured, comprehensive resource designed for researchers, clinicians, and informed readers seeking a rigorous understanding of peptide science.
Each chapter in this series offers a focused, stand-alone deep dive into a specific area of peptide science. Together, these chapters form a complete educational framework that explains the chemistry, structure, analytical methods, stability considerations, pharmacokinetics, delivery strategies, research applications, limitations, future trends, and laboratory practices essential for working with peptides.
