Lipids traditionally have been viewed as serving two functions: to form cellular membranes and to serve as energy stores. During the last two decades, a new role for lipids has taken center stage: lipids can act as signalling molecules. This book deals with a variety of lipids that have been shown to be messengers. Leading scientists explore all known lipid classes except steroid hormones. Researchers and educators in biochemistry as well as in molecular and cellular biology will appreciate this volume.
