This section provides the following information:

  • GlyTouCan Accession - Unique identifier assigned to the registered glycan structure in the GlyTouCan database. Eg. G17689DH
  • Monoisotopic Mass - Monoisotopic mass of the glycan in Daltons. Eg. 2,368.84 Da
  • Monoisotopic Mass-pMe (Da) - Permethylated monoisotopic mass of the glycan in Daltons. Permethylation involves the addition of methyl groups (CH3) to all of the hydroxyl and N-acetyl groups and also methyl esterifies the carboxy function on sialic acid. Eg. 2,368.84 Da
  • Composition - Monosaccharide composition of the glycan represented by the number of each class of monosaccharide. Eg. Hex5HexNAc4dHex1NeuAc2
  • Byonic™ - Glycan sequence in Byonic format. Eg. Hex(5)HexNAc(4)dHex(1)NeuAc(2)
  • Glycan Type / Glycan Subtype - Glycan classification, defined by type and subtype. Eg. N-linked  /  Core-fucosylated
  • InCHI Key - International Chemical Identifier hash (InChIKey) computed from chemical structure using the International Union of Pure and Applied Chemistry (IUPAC) standard. Eg. YWJPMIROECFZJW-YBQNOACISA-N
