Largest Synthetic Polysaccharide Assembled

Linear 100-mer polysaccharide within 188 hours

05-May-2020

Chemists at the Max Planck Institute of Colloids and Interfaces (Potsdam, Germany) have set a milestone by preparing the two largest carbohydrates ever assembled. Using an Automated Glycan Assembly (AGA) instrument originally developed at the institute they prepared a linear 100-mer and achieved ...
