 Title    Complexation of Tertiary Amides by Phenols in Carbon Tetrachloride Solutions  
 Abstract    Formation constants for 1 : 1 complexes of N,N-dialkylamides and N-acetylmorpholine with chloro-and nitrophenols have been determined spectrophotometrically in carbon tetrachloride solutions at 20 °C. Enthalpies of reaction for 14 systems have been obtained calorimetrically. Dipole moments of N,N-di(n-butyl)acetamide, N,N-di(isobutyl)acet-amide and N-acetylmorpholine have been determined.

 Title    Metabolism of Benzoic Acids and Phenols in Cell Suspension Cultures of Soybean and Mung Bean  
 Abstract    Uptake of benzoic and salicylic acid by soybean cell suspension cultures is diffusion-mediated and exclusively leads to glucose-esters. — Veratric acid is para-demethylated to vanillic acid which is conjugated to a monoglucoside. — Nitrobenzoic acids are scarcely taken up by cell cultures with glucose-esters as sole products. — Ring-labelled derivatives of vanillylalcohol and creosol are mainly polymerized to insoluble structures, ring cleavage reactions could not be observed.

 Title    Evidence for the Existence of meta and para Directing O-Methyltransferases in Tobacco Cell Cultures  
 Abstract    The O-methyltransferase of tobacco cell culture was resolved to its meta and para directing forms by chromatography on DEAE-cellulose. Despite similarities in molecular weights and pi values of the two forms, however, evidence from pH optima, SH-group inhibitors, methylation ratios, SDS-acrylamide gels and mixed substrate experiments indicates the existence of two discrete enzymes acting at the meta and para positions of caffeic acid and quercetin, respectively; though the latter enzyme was less substrate specific than its meta counterpart.
