Lipids

For the 6th Edition of this highly regarded textbook devoted to lipids, the title has been modified from Lipid Biochemistry to Lipids to acknowledge the coming together of biological and medical sciences, the increasingly blurred boundaries between them and the growing importance of lipids in diverse aspects of science and technology. The principal aims of this new edition - to inform students and researchers about lipids, to assist teachers and encourage further research - have not changed since previous editions.

Significant advances in lipid science have demanded yet another extensive rewriting for this edition, with the addition of two new authors, to cover new knowledge of genes coding for proteins involved in lipid metabolism, the many lipids involved in cell signalling, the roles of lipids in health and disease and new developments in biotechnology in support of agriculture and industry.

An introductory chapter summarizes the types of lipids covered and their identification and provides a guide to the contents. Chapters contain boxes illustrating special topics, key point summaries and suggested further reading.

Lipids: Sixth Edition provides a huge wealth of information for upper-level students of biological and clinical sciences, food science and nutrition, and for professionals working in academic and industrial research. Libraries in all universities and research establishments where biological, medical and food and nutritional sciences are studied and taught should have copies of this excellent and comprehensive new edition on their shelves.
