“…Alteration of N-glycans has been observed in various diseases and, specifically, fucosylation of the N-glycoproteins has been frequently associated with the diseases of the liver. [1][2][3][4][5][6][7] In human tissues, fucosylation of N-glycans takes place on the innermost GlcNAc (core fucosylation) by α−1,6 linkage, or on the outer arms by an α−1,2 linkage to a galactose (often terminal), or α−1,3 or α−1,4 linkage to the mostly subterminal GlcNAc based on the activity of specific fucosyltransferases. 8 The linkage of fucose, especially the core versus outer arm fucosylation, is an important determinant of the N-glycoprotein interactions and activities.…”
