The formation of furanose structure of fructose involves the interaction of functional groups present at:
1 C-1 and C-4
2 C-2 and C-6
3 C-2 and C-5
4 C-1 and C-5
Explanation:
The formation of furanose structure of fructose involves the interaction of keto group (C2) with -OH of C5.

Assign the configuration to glyceraldehyde (I) and glucose (II). Choose the correct option.
In (+) glucose, \(\mathrm{-\mathrm{OH}}\) on the lowest asymmetric carbon is on the right side which is comparable to \(\mathrm{(+)}\) glyceraldehyde so it is assigned as D-configuration. The most oxidised carbon is at the top in the structure.
