Synlett 2003, No. 4, Print: 12 03 2003. Art Id.1437-2096,E;2003,0,04,0542,0546,ftx,en;D28903ST.pdf. © Georg Thieme Verlag Stuttgart · New York ISSN 0936-5214 Abstract: Treatment of an α-amino acid with N-bromosuccinimide in water at pH 5 or in an alcoholic-aqueous ammonium chloride mixture, followed by addition of nickel(II) chloride and sodium borohydride, effected an overall decarboxylation v...
متن کاملThe decarboxylation of amino acids, proteins, and peptides by N-bromosucclnimide.
One of the most widely used methods for the determination of amino acids is the ninhydrin technique perfected by Van Slyke and his coworkers (1). This permits the measurement of amino acid concentration either calorimetrically or by the volume of carbon dioxide released during the reaction. The measurement of carbon dioxide by the Van Slyke manometric apparatus is capable of great precision but...

متن کاملHydroxylation and decarboxylation of hydroxybenzoic acids by Fe -chelates
4 2 containing FeSO and Na EDTA. EDTA could be replaced by citric acid. In this in vitro system 4hydroxybenzoic acid is hydroxylated to 3,4-dihydroxybenzoic acid (protocatechuic acid) and decarboxylated to hydroquinone. In an analogous reaction 2-hydroxybenzoic acid (salicylic acid) is hydroxylated to 2,3-dihydroxybenzoic acid and 2,5-dihydroxybenzoic acid (gentisic acid) and decarboxylated to ...
متن کاملDetermination of aspartic and glutamic acids by enzymatic decarboxylation.
Suspensions of Clostridium welchii (strain SR 12) quantitatively decarboxylate the L isomers of aspartic (1) and glutamic acids (2) to ar-alanine and y-aminobutyric acid, respectively. Although a quantitative procedure for the determination of glutamic acid based upon decarboxylation with this organism has been described (3), it has been found that aspartic acid, especially in the presence of c...
