Application

N-(4-Aminobenzoyl)-L-glutamic acid (ABG) is used as a strong UV absorbing tag for the derivitization of oligosaccharides to enhance their detection in analytical methods such as capillary zone electrophoresis (CZE).

Biochem/physiol Actions

N-p-Aminobenzoyl)-L-glutamic acid is a folate catabolite that can be metabolized by bacterial p-aminobenzoate auxotrophs possessing the enzyme p-aminobenzoyl-glutamate hydrolase.

A charged and strongly UV-absorbing tag, N-(4-aminobenzoyl)-L-glutamic acid) (ABG), was coupled to oligosaccharides by reductive amination under mild conditions. The effectiveness of ABG as a derivatization agent is shown through the separation of isomaltooligosaccharides from a dextran hydrolysate. The minimum

The development of accurate and precise folate assays has been difficult, mainly because of folate instability. Large interassay and interlaboratory differences have been reported. We therefore developed a serum folate assay that measures folate and putative degradation products as p-aminobenzoylglutamate

In a 10-wk study of folate metabolism in nonpregnant women (21-27 y, n -6 per group), subjects were fed a diet containing approximately 68 nmol/d (30 microg/d) folate from food. The remainder of the ingested folate was provided as folic

Measurement of the urinary folate catabolites, para-aminobenzoylglutamate (pABG) and the more predominant acetylated form, acetamidobenzoylglutamate (apABG), has been used to assess folate requirements in both pregnant and nonpregnant women. Folate catabolite excretion has been reported to be significantly higher in

Mice have three arylamine N-acetyltransferase (NAT) isoenzymes (NAT1, NAT2, and NAT3) of which NAT2 is known to be polymorphic. Humans have two polymorphic isoenzymes, NAT1 and NAT2. The isoenzymes mouse NAT1 and human NAT2 are expressed predominantly in the liver
