This book presents the latest developments in glycoscience and outlines a roadmap for the next decade, reflecting Japan?s leadership in this rapidly evolving field. Building on the previous edition, Glycoscience: Basic Science to Applications (2019), the Japan Consortium for Glycobiology and Glycotechnology (JCGG) has compiled this revised edition to foster global collaboration and accelerate innovation across the life sciences. This edition contains 167 entries contributed by 170 experts and is organized into six thematic parts: emerging glycan technologies; medicine, healthcare, and diseases involving glycans; glycan-related pharmaceuticals; glycan-related foods and their functions; glycan-based functional materials; and glycoinformatics. Each entry offers a structured overview of the topic?s current status, scientific and societal impact, industrial applicability, and future challenges. The book is a distinctive and valuable resource for researchers, students, clinicians, industry professionals, and policymakers. It promotes interdisciplinary integration, supports education and outreach, and serves as a strategic guide for advancing glycoscience globally.
