Glucose as well as fructose are oxidized by periodic acid. The number of moles of $\mathrm{HCOOH}$, formed from each mole of glucose and fructose are:

Draw the Fischer projections for the open-chain structures of D-glucose and L-glucose?

The fischer projection of D-fructose is given below, write the fischer projection of L-fructose.

Write the reaction of D-glucose with ${\mathrm{HNO}}_3$.

Give reasons as the evidence in support of cyclic structure of glucose
