AROMATIC COMPOUNDS 



7. The methoxyl groups present on many natural aromatic compounds are derived 

 from the usual biological methyl donors such as methionine, formate, and the 

 i3-carbon of serine (59). 



8. Experiments with partially purified enzyme systems have begun to provide con- 

 firmation that the reactions shown do occur in higher plants and have opened 

 the way to a clearer understanding of the details of the various transformations 

 (51,60,61,62).
