There is this common fallacy when dealing with chemistry that compounds with close structures (or substructures) are the same or have related effects. You can find benzene rings as a substructure of some amino acids all over your proteins doesn't mean eating protein will poison you with benzene...

Sometimes just as little as a change in the spatial configuration of a compound (cis/trans isomers for example) or the addition of a carbon can dramatically change the effect of a molecule on a living body...
