    Don’t be too impressed! I do know that there are many different sugars, but for some reason I’d forgotten that many of the familiar sugars are disaccharides. In other words, if someone had asked me for the chemical formula for sucrose, I probably would have responded (wrongly) C6 H12 O6.

    After Robert Baden’s comment became visible to me, I looked up sucrose and found it’s actually C12 H22 O11 (standard double-sugar chemical formula). Ah, how a little knowledge can be a dangerous thing!
