Introduction to Peptide Science

Provides an interdisciplinary introduction to peptide science, covering their properties and synthesis, as well as many contemporary applications Peptides are biomolecules comprised of amino acids which play an important role in modulating many physiological processes in our body. This book presents an interdisciplinary approach and general introduction to peptide science, covering contemporary topics including their applicability in therapeutics, peptide hormones, amyloid structures, self-assembled structures, hydrogels, and peptide conjugates including lipopeptides and polymer-peptide conjugates. In addition, it discusses basic properties and synthesis clearly and concisely. Taking a logical approach to the subject, Introduction to Peptide Science gives readers the fundamental knowledge that is required to understand the cutting-edge material which comes later in the book. It offers readers in-depth chapter coverage of the basic properties of peptides; synthesis; amyloid and peptide aggregate structures; antimicrobial peptides and cell-penetrating peptides; and peptide therapeutics and peptide hormones. Introduces readers to peptide science, including synthesis and properties Provides unique content covering properties, synthesis, self-assembly, aggregation, and applications Summarizes contemporary topics in an accessible fashion including applications in therapeutics, peptide hormones, amyloid structures, self-assembled structures, hydrogels, and peptide conjugates including lipopeptides Presented at an introductory level for the benefit of students and researchers who are new to the subject Introduction to Peptide Science is an ideal text for undergraduate students of chemistry, biochemistry, and other related biological subjects, and will be a valuable resource for postgraduate students and researchers involved in peptide science and its applications.
