This 3rd edition of H.W. Heldt's Plant Biochemistry textbook is built around proven artwork from previous editions, with some intelligent additions. It adds substantial new text and more references than in the past that can guide the reader to in-depth studies, often with references from 2004, clearly this textbook is not outdated. This edition places much emphasis on concepts that are presented in lucid fashion, providing an insight into complex processes in a straightforward way. This is particularly obvious in those areas of plant biochemistry that have been the author's own field of research for several decades. This textbook is an excellent vehicle to make green biochemistry understandable to undergraduate students.
