  • enzymes
  • Chorismate is transformed into para-aminobenzoic acid by the enzymes 4-amino-4-deoxychorismate synthase and 4-amino-4-deoxychorismate lyase. (wikipedia.org)
  • In these enzymes, the flavin plays either a direct role in acid/base reactions or as a nucleophile or electrophile. (mdpi.com)
  • sulfuric acid
  • Sulfuric acid dissolves it, forming a deep-red solution. (wikipedia.org)
  • It dissolves in concentrated sulfuric acid with a yellowish-green fluorescence. (wikipedia.org)
  • The rhodamines, which are closely related to the phthaleins, are formed by the condensation of the alkyl metaaminophenols with phthalic anhydride in the presence of sulfuric acid. (wikipedia.org)
  • Examples include the original Boots method which involves nitration of phenol with sulfuric acid and sodium nitrate giving a mixture of two isomers, from which the desired 4-nitrophenol is separated by steam distillation. (google.com)
  • synthase
  • Other names in common use include: 5-enolpyruvylshikimate-3-phosphate synthase, 3-enolpyruvylshikimate 5-phosphate synthase, 3-enolpyruvylshikimic acid-5-phosphate synthetase, 5'-enolpyruvylshikimate-3-phosphate synthase, 5-enolpyruvyl-3-phosphoshikimate synthase, 5-enolpyruvylshikimate-3-phosphate synthetase, 5-enolpyruvylshikimate-3-phosphoric acid synthase, enolpyruvylshikimate phosphate synthase, and 3-phosphoshikimate 1-carboxyvinyl transferase.

  • phthalic anhydride
  • Industrially it is produced from phthalic anhydride, beginning with amination: C6H4(CO)2O + NH3 + NaOH → C6H4(C(O)NH2)CO2Na + H2O The resulting sodium salt of phthalamic acid is decarbonylated via a Hofmann rearrangement of the amide group, induced by hypochlorite: C6H4(C(O)NH2)CO2Na + HOCl → C6H4NH2CO2H + NaCl + CO2 A related method involves treating phthalimide with sodium hypobromite in aqueous sodium hydroxide, followed by neutralization.

  • strains
  • Similarly, phenazine-1-carboxylic acid, produced by a number of Pseudomonas, increases survival in soil environments and has been shown to be essential for the biological control activity of certain strains. (wikipedia.org)
  • production
  • The present disclosure provides compositions and methods for the biosynthetic production of acetaminophen, p-aminophenol, and p-aminobenzoic acid and the purification of biologically derived acetaminophen. (google.com)
  • The present disclosure relates compositions and methods for the biosynthetic production of medicinal supplements such as acetaminophen and intermediates including p-aminophenol, poly(p-aminophenol), and p-aminobenzoic acid (PABA). (google.com)
  • Figure
  • Figure 10.18 Dihydromatricaria acid is found in cantharid beetles feeding on Compositae which contain polyacetylenic acids. (phrygane.tk)
