Preface

This book, Nutritional Biochemistry–I, is designed to provide a comprehensive foundation in the biochemical principles underlying human nutrition, with a particular focus on the structure, function, and metabolism of macronutrients and nucleic acids. Organized into four major credits, the text begins with an in-depth exploration of carbohydrates, covering their classification, dietary sources, physiological functions, digestion, absorption, and regulation of blood glucose, along with detailed biochemical pathways such as glycolysis, the TCA cycle, electron transport chain, pentose phosphate pathway, glycogenesis, and glycogenolysis, while also addressing alcohol metabolism and inborn errors like glycogen storage diseases and lactose intolerance. It then progresses to amino acids, emphasizing their chemical nature, nutritional classification, metabolic pathways including transamination and deamination, the urea cycle, and the metabolism of aromatic and branched-chain amino acids, alongside associated genetic disorders such as PKU and maple syrup urine disease. The third section focuses on proteins, discussing their classification, digestion, transport, and utilization, as well as the intricate process of protein biosynthesis, including genetic coding, initiation, elongation, termination, and post-translational modifications. Finally, the book examines nucleic acids and nucleotide metabolism, detailing the synthesis and degradation of purines and pyrimidines, the structure and function of DNA and RNA, and related metabolic disorders such as gout and Lesch-Nyhan syndrome. Supported by recommended textbooks and references, this volume aims to equip students with both theoretical knowledge and clinical relevance, fostering a clear understanding of how biochemical processes influence nutrition, health, and disease.
