- •
Hemiesters of carbonic acid and sugars are spontaneously formed in aqueous solutions.
- •
Isomers are formed according to the reactivity of the hydroxy group.
- •
Higher concentrations of carbonate are observed for sugars with a primary alcohol.
- •
d-Glucopyranose 6-carbonate corresponds to 74% of the glucose carbonate in water.
