WebIt could be shown that the reaction of binding of nitrogen started at pH values higher than 6.5, and that only such phenols reacted which had no methoxylated hydroxyl groups. The reaction of some phenols during oxidation in presence of amino acids was accompanied by deamination and decarboxylation of the latter. WebThe formation of an N -hydroxysuccinimide ester by reaction of the carboxylic acid group with N -hydroxysuccinimide (NHS), frequently in the presence of dicyclohexylcarbodiimide, is another carboxylic acid mediated reaction, and one that is frequently used in preparing conjugates for contaminant immunoassays.
