PANTOTHENIC ACID 



Pantothenic acid also prevented the toxic action of 2-chloro-4- 

 aminobenzoic acid on E. coli, being even more effective than ^-amino- 

 benzoic acid. At high levels of the inhibitor, antagonism was more 

 complete when methionine as well as pantothenic acid was present.** 

 It is not known what stage of pantothenic acid synthesis is affected 

 by 2-chloro-4-aminobenzoic acid.
