Glycans (carbohydrates, sugars, monosaccharides, oligosaccharides and polysaccharides) are widely distributed in nature, in all living life forms. There is much useful glycoscience content at NCBI, including many publications discussing glycans, chemical records containing glycans, macromolecules containing glycans, biosynthetic pathways involving glycans, proteins and genes involved in glycobiology, diseases involving glycans, and books dedicated to glycoscience. This page, as a dedicated glycan information site in NCBI, highlights some useful resources for better integrating the study of glycans into the mainstream of biology, and will be further developed over time, based on interest and usage by the scientific community.
