Reduction reaction

Aldoses and  ketoses are  reduced  to  the corresponding polyhydroxy  alcohols by sodium borohydride, sodium amalgam, etc. So,  in  this  reaction,  glucose is reduced to glucitol (sorbitol).

Polyhydric alcohols are also called sugar alcohols and are the hydrogenated forms of the aldoses or ketoses. Glucitol, also known as sorbitol, has the same linear structure as  the  chain  form  of  glucose, but  the  aldehyde  (-CHO)  group is  replaced  with a -CH20H group (at C-1).
