Structure Determination

Structure Determination: A Biological Approach to Molecular Structure provides a clear and accessible introduction to the fundamental principles and techniques used to determine the structure of molecules of biological importance. Designed for undergraduate students, the book connects the principles of chemistry and molecular structure with biological concepts and applications. Beginning with the fundamental concepts of molecular structure, the book introduces students to major experimental and computational approaches used in structural science. Topics include spectroscopy, UV-Visible spectroscopy, infrared spectroscopy, mass spectrometry, X-ray crystallography, and other important methods for investigating molecular structure and behavior. Throughout the book, theoretical principles are presented together with biological examples to help students understand how structural information is obtained and interpreted. Particular attention is given to the relationship between molecular structure, physical properties, and biological function. Examples involving proteins, nucleic acids, pigments, enzymes, and other biologically relevant molecules demonstrate how structure-determination techniques contribute to modern biology, biochemistry, and molecular research. The book is written in a step-by-step manner, with emphasis on conceptual understanding rather than purely mathematical treatment. Equations and scientific principles are introduced in a form appropriate for undergraduate learners, while biological applications help connect theoretical knowledge with practical scientific problems. This textbook is intended primarily for undergraduate biology students, while also providing a useful introductory resource for students in biochemistry, biotechnology, chemistry, and related fields. It may serve as a foundation for further study in structural biology, molecular biology, biochemistry, and computational molecular science.
