Galacturonic Acid Analysis Service

MtoZ Biolabs employs advanced instruments and analytical platforms to offer the galacturonic acid analysis service which enables precise qualitative and quantitative detection of galacturonic acid in various samples. This service is widely applied in pectin structure elucidation, plant cell wall research, and polysaccharide degradation mechanism studies, providing reliable data support for functional polysaccharide research and biomass utilization.

 

What Is Galacturonic Acid?

Galacturonic acid is a monosaccharide derivative formed by the oxidation of D-galactose and serves as an essential structural unit of pectin and many plant polysaccharides. It typically exists in plant cell walls through α-1,4-glycosidic linkages, playing a critical role in maintaining cell wall stability, regulating plant growth, and facilitating pectin degradation. Because of its close relationship with polysaccharide structure and biological function, galacturonic acid analysis is widely applied in phytochemistry, biomass utilization, and polysaccharide functional research.
