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
