Caffeine and Chocolate Molecules Earrings

Get your geek on with this set of molecules! Caffeine and theobromine-a molecule found in chocolate-are structurally similar, with the difference being an additional methyl group bonded to a nitrogen. The methyl groups are represented by a triple picot; the double-bonded oxygens are represented by an open picot. (For supergeeks, 1,3,7-trimethylpurine-2,6-dione and 3,7-dimethylpurine-1H-2,6-dione are the systematic names for caffeine and theobromine, respectively.)
