Fig. 2. Glycans used for the training of GlyNet. (A) Distribution of the glycan sizes and examples of bi- and tri-antennary glycans with 20, 27 and 36 monosaccharides. (B) Distribution of monosaccharide occurrences within the 599 glycans. (C) Distribution of the different anomeric link occurrences within the glycans. (D) Details of the modified monosaccharides, showing for each of the four modifications/positions a list of the monosaccharides with that modification and their frequencies.
