Fructose (fruit sugar) is a monosaccharide - formula C6H12O6.
It is also another 6-carbon (hexose) sugar.
Notice the 6 carbon atoms (grey) forming the backbone of the molecule, and the oxygen atom (red) in the ring - which is a 5 sided ring, unlike in glucose.
The hydrogen atoms (white) are either attached directly to the carbons, or via oxygen as OH groups - at an angle.
Only the two carbons outside the ring ( number 1 & 6) have 2 single hydrogens and an OH group.
