Chemische Biologie -- was ist wirklich wichtig? Die Herausgeber dieses Bandes lassen die Praxis selbst die Maßstäbe setzen. Anhand von Fallstudien aus dem Laboralltag, ausgewählt und kommentiert von erfahrenen Autoren, lernt der Leser, bei der Lösung biologischer Probleme die richtigen Prioritäten zu setzen und geeignete Methoden aus der Chemie sinnvoll anzuwenden. Ein motivierendes Buch -- nicht nur für Studenten! This first book to adopt a problem-based approach teaches the true basics of the subject through illustrated everyday case studies. The editor's extensive experience in writing textbooks and his close relationship to the authors ensure that the contributions are presented in a pedagogically uniform and highly motivating fashion.
