This book is a excellent hand book which is systematically organized and well-documented on the role of bile acids in liver and hepatobiliary diseases. However, the book includes the role of biosynthesis of primary and secondary bile acids from cholesterol as well as highlights their regulation with the clinical significance. It has also a good review on the clinical importance of various bile acids along with their serum level in patients of liver and hepatobiliary complications. -Dedicated to my Father, Late Mr. Ram Kumar Sharma and my Mother Mrs. Sushila Sharma
