Human Cholinesterases and Anticholinesterases summarizes the many fundamental concepts of human cholinesterases (ChEs) and their inhibitors. This book is divided into three chapters that represent human cholinesterase research studies from different points of view. Chapter 1 deals with the biochemical and biological background of human ChEs. This chapter also examines the molecular polymorphism, genomic origin, genetic variants, and biological roles of these enzymes. Chapter 2 provides the molecular characterization of human ChE genes and their multileveled regulation, with a special emphasis on butyrylcholinesterase. Chapter 3 discusses the scientific, ecological, and clinical implications of the studies presented in the previous chapters. Protein scientists, engineers, and researchers will find this work invaluable.
