  1. Hex hexose, HexNAc N-acetylhexosamine, dHex deoxyhexose
  2. C. molossus glycosaminoglycan (CaG) constituted of hexoses in the 3 K Da under fraction, Hex3HexNAc3dHex1 (1282.5 m/z) and Hex8 (1337.5 m/z) N-glycan glycosylation structure. IQG N-glycan had the glycosylation structure of the Hex3HexNAc3dHex1 (1282.5 m/z) or Hex4HexNAc3dHex1 (1485.6, m/z). HEG N-glycan had the glycosylated Hex7 (1175.2 m/z) and Hex7HexNAC6 (1752.2 m/z)
