Cyclic β-glucans at the bacteria–host cells interphase: One sugar ring to rule them all [PDF]

open access: yes, 2018
Cyclic β‐1,2‐D‐glucans (CβG) are natural bionanopolymers present in the periplasmic space of many Proteobacteria. These molecules are sugar rings made of 17 to 25 D‐glucose units linked exclusively by β‐1,2‐glycosidic bonds.
