Challenges The complexity of sugars: regarding their structures, they are not linear instead they are highly branched. Moreover, glycans can be modified (modified sugars), this increases its complexity. Complex biosynthetic pathways for glycans. Usually glycans are found either bound to protein (glycoprotein) or conjugated with lipids (glycolipids). Unlike genomes, glycans are highly dynamic.
