Usage

General Description

D-Galacturonic acid methyl ester is a chemical compound derived from galacturonic acid, a type of sugar acid. It is commonly used as an intermediate in the production of pectin, a natural substance found in the cell walls of plants that is used as a gelling agent in food products. D-Galacturonic acid methyl ester is also used in the synthesis of pharmaceuticals and other organic compounds. It has several industrial applications, including as a flavoring agent and as a component in biodegradable polymers. Additionally, it has potential uses in the development of drug delivery systems and as a substrate for enzymatic reactions.

D-Galacturonic Acid: A Highly Reactive Compound in Nonenzymatic Browning. 2. Formation of Amino-Specific Degradation Products

Thermal treatment of aqueous solutions of D-galacturonic acid and L-alanine at pH 3, 5, and 8 led to rapid and more intensive nonenzymatic browning reactions compared to similar solutions of other uronic acids and to Maillard reactions of reducing sugars. The hemiacetal ring structures of uronic acids had a high impact on browning behavior and reaction pathways. Besides reductic acid (1,2-dihydroxy-2-cyclopenten-1-one), 4,5-dihydroxy-2-cyclopenten-1-one (DHCP), furan-2-carboxaldehyde, and norfuraneol (4-hydroxy-5-methyl-3-(2H)-furanone) could be detected as typical products of nonenzymatic uronic acid browning reactions. 2-(2-Formyl-1H-pyrrole-1-yl)propanoic acid (FPA) and 1-(1-carboxyethyl)-3-hydroxypyridin-1-ium (HPA) were identified as specific reaction products of uronic acids with amine participation like L-alanine. In contrast, the structurally related D-galacturonic acid methyl ester showed less browning activity and degradation under equal reaction conditions. Pectin-specific degradation products such as 5-formyl-2-furanoic acid and 2-furanoic acid were found but could not be verified for D-galacturonic acid monomers alone.
