The Pentose Phosphate Pathway aims to explore the pentose phosphate cycle and the practical techniques applied in its investigation. The main focus of the book is the pentose phosphate cycle in animals as well as microorganisms, and does not discuss the one related to photosynthesis. The book covers the formulation of the pathway, its types, and its alternative formulations; the preparation, processes, and analysis of the pathway; and the enzymes involved. Also covered in the book are the intermediates in intact cells and tissues; distribution of enzymes among different tissues and species; the operation, regulation, and overall control of the pathway; and the clinical, nutritional, and metabolic aspects of the pathway. The text is recommended for biologists and biochemists who would like to understand further the pentose phosphate pathway and the processes related to it.
