Biochemistry and clinical chemistry have long been an established part of pharmaceutical education. A comprehensive knowledge of the molecular processes in the human body is needed for a detailed understanding of disease pictures and of drug action at the molecular level. These subjects are of supreme relevance for pharmaceutical practice – without the methods of biochemistry and molecular biology, the development of new active substances is inconceivable. However, to date the established reference works have covered a much too broad range of topics, go into excessive detail and are not geared to the study of pharmacy. This textbook finally fills this gap in a hitherto unique way. Thanks to the concise learning content, it is tailored to the needs of pharmacy students. The authors therefore concentrate on the material required for the registration examination and focus on topics of relevance to drugs and treatment. They summarise the biochemical principles and use selected examples to explain the connections between them. Numerous diagrams, pictures and info boxes provide structure to the subject matter, facilitate learning and make reading enjoyable.
