Glycome: The Hidden Code in Biology addresses one of the most fundamental questions in biology today. The book targets readers with little expertise as well as the experts in Glycoscience.

Sugars are electroneutral. However, linking sugars to sugars, or attaching sugars to proteins or lipids changes the structural and functional identities of the glycoconjugate, and enables to form cellular networks of 4Gs [i.e., glycoproteins (N-linked or O-linked), glycosphingolipids, proteoglycans and glycosaminoglycans (GAGs)]. These glycans (i) support growth, proliferation and differentiation of cells and tissues; (ii) protect cells from foreign invasions including bacteria, viruses, parasites as well as from changes in the extracellular environment; (iii) act as biomarkers and participate in transmembrane signaling. The glycans are not ubiquitous but they are tissue/species specific.

Structurally, the glycans are diverse, and form linear to highly branched structures. This diversity is present not only across the species but also within cells of the same species, i.e., the glycoforms. Nuclear magnetic resonance (NMR) and mass spectrometric (MS) studies (i.e., Glycomics) have evaluated and contributed significantly in delineating the structural diversity of glycans. Glycomics, in fact, has helped in overcoming many earlier technological barriers which were otherwise very laborious and time consuming. Plant lectins being carbohydrate binding proteins with a high degree of sugar specificity have been useful tools to characterize the carbohydrate structures they recognize.

The glycan structures complement their biosynthetic processes. Because of the highly compartmentalized nature of the process, the glycans move between compartments during their assembly. This is believed to be mediated by vesicular structures but the participation of exosomes cannot be ruled out.
A large number of genetic disorders [gangliosidosis, mucopolysaccharidoses, congenital disorders of glycosylation (CDG)] are due to abnormal glycan synthesis or degradation. Disproportionate expression of glycans is also found in diseases like cancer, neurological disorders, diabetes, metabolic syndromes, and infection. This raises questions about the regulatory principle(s) in glycan biosynthesis.

There is no template for glycan chain synthesis, elongation, processing or termination. The cells/tissues follow a highly conserved mechanism. The assumption is glycosylation uses donor and acceptor interactions as the driving force. Increased or decreased synthesis of glycans in response to the environmental change influence cell function, i.e., growth, survival or death favor of a “push-pull” hypothesis. In the absence of a genetic code for sugars, the assembly as well as the processing of glycan chains are controlled by the Glycome. Unlike the genome, the Glycome is hidden for the normal eye but its communication skills with the cellular microenvironment and genome for glycan synthesis and degradation are enormous. Seventeen chapters in the book are dedicated to walk the readers through the diversities of the Glycome. The authors have used mammalian, microbial and plant systems to achieve the desired goal.

“We now know that glycans embed specific information in their 3D structures recognised by other macromolecules. This book provides a wonderful and timely collection of diverse topics on the latest developments in the generation of tools to study glycans, the role of glyco codes in a range of physiological responses in mammals and plants and the impact of altered glycosylation in disease. This will be a highly valuable resource for both beginners and experts in the glycobiology field, a pivotal discipline for biology.” – Paul A. Gleeson, PhD, Professor, Department of Biochemistry and Molecular Biology, The University of Melbourne, Melbourne, Victoria, Australia

“The diverse compositions and structures of glycans and polysaccharides that modify the majority of intracellular and extracellular proteins have critical functions in most cellular biology from birth to growth, to maintenance of adulthood, to pathologies. This book identifies the very large variety of normal and pathological cellular functions and processes that rely on the glyco structures involved. I highly recommend that researchers, especially young investigators, read the relevant chapters to learn how glycobiology can have a major impact on their ongoing and future research.” – Vincent Hascall, PhD, Biomedical Engineering, Lerner Research Institute, Cleveland Clinic, Cleveland, OH, USA
