Human Biochemistry, Second Edition provides a comprehensive, pragmatic introduction to biochemistry as it relates to human development and disease. Here, Gerald Litwack, award-wining researcher and longtime teacher, discusses the biochemical aspects of organ systems and tissue, cells, proteins, enzymes, insulins and sugars, lipids, nucleic acids, amino acids, polypeptides, steroids, and vitamins and nutrition, among other topics. Fully updated to address recent advances, the new edition features fresh discussions on hypothalamic releasing hormones, DNA editing with CRISPR, new functions of cellular prions, plant-based diet and nutrition, and much more.
Grounded in problem-driven learning, this new edition features clinical case studies, applications, chapter summaries, and review-based questions that translate basic biochemistry into clinical practice, thus empowering active clinicians, students and researchers
