galacturonic acid
Sugar acid derivative
Galacturonic acid is a sugar acid derived from galactose, serving as the primary building block of pectin—the substance that gives jams and jellies their gel.
It occurs naturally in plant cell walls, where pectin provides structural support.
The compound is important in food science and plant biology.
