What is the chemical basis of this reactivity? β-DGlucose

β-D-Glucose is the most prevalent monosaccharide in the bloodstream. It can react with many differentcompounds. What is the chemical basis of this reactivity?
by

1 Answer

Answer :

Glucose is an aldehyde and hence is a reducing compound. The aldehyde group is reactive and can be reduced to form an alcohol, can be oxidized to form a carboxylic acid, or can react with many other compounds to form a glucosyl adduct with them.
