Part Descriptions
LP15353-3 Alpha aminobutyrate
Alpha-Aminobutyric acid (AABA) is an isomer of the amino acid aminobutyric acid with chemical formula C4 H9 NO2. There is also gamma-aminobutyric acid (GABA) and beta-aminobutyric acid. It is a key intermediate in the biosynthesis of ophthalmic acid or ophthalmate, which was first isolated from calf lens.

LP15353-3 Alpha aminobutyrate
Alpha amniobutyric acid (AABA), also known as Alpha-amino-N-butyric acid (A-ANB), is an intermediate formed during the catabolism of methionine and threonine. Increases in AABA occur secondary to elevations of either methionine or threonine. AABA becomes propionic acid via alpha-ketobutyric acid in the presence of adequate amounts of thiamin, vitamin B2(as FAD), vitamin B3(as NAD), lipoic acid and magnesium. Deficiencies of any of these, or vitamin B6, could cause increases in AABA. Elevated or decreased levels of the amino acid may indicate a congenital enzyme defect.
