Description of the core N-glycan structure. Glycan structures are expressed as graphs using symbols that are defined by the CFG. Each monosaccharide is signified as a node and each glycosidic bond is indicated as an edge. The reducing terminal is the root which binds to proteins and lipids, and the non-reducing terminal is the opposite side, known as leaves. Adjacent nodes have parent–child relationships, with the node on the root side being the parent. Children having the same parent are defined as siblings
