Cancer Res. 29, 925-937, 1969 “Every eukaryotic cell is covered with a dense and complex array of glycans.” … in fact… “Evolution has failed to generate a [single] living cell devoid of surface glycosylation”- A. Varki

  19. Glycobiology • Introduction to Glycobiology • Glycan structures • Glycan functions

  20. Glycobiology • Introduction to Glycobiology • Glycan structures • Glycan functions • Just nine monosaccharide saccharide building blocks are responsible for building nearly all mammalian glycans. • All are six-membered rings (5 carbons, 1 oxygen) varying in the substituents at each carbon (mostly hydroxyls). • Seven are closely structurally related to glucose.

  21. Seven sugars and their structural relationship to glucose Taylor & Drickamer (2011) Introduction to Glycobiology, 3rd edition

  22. Two important terminal eukaryotic sugars Taylor & Drickamer (2011) Introduction to Glycobiology, 3rd edition

  23. Monosaccharides equilibrate between open chain and ring forms.For each monosaccharide, two ring forms (anomeric configurations) are possible, α and β

  24. When a glycosidic bond is formed,the anomeric configuration is “locked”

  25. Nomenclature: -Name the non-reducing (left-most) sugar (Gal) -Name the anomeric configuration (β) -Name the anomeric carbon number (1) -Name the substituted carbon number (4) -Name the substituted sugar (Glc) RESULT: Gal β1-4 Glc

  26. Nomenclature: Branches are placed in parentheses NeuAc α2-3 Gal β1-4 (Fuc α1-3) GlcNAc

  27. NeuAc α2-3 Gal β1-4 (Fuc α1-3) GlcNAc
