What is it?
Polygalacturonic acid, (C6H8O6)n), also known as pectic acid or pectin, is a gelatinous acid that exists in some fruits and vegetables. In land plants, polygalacturonic acids are major components of cell wall polysaccharides (pectins). It may be formed by partial or complete hydrolysis of pectin esters. Polygalacturonic acid may be used to identify, differentiate and characterized plant cell wall degrading polygalacturonase(s) from fungi. Pectins are also used as emulsifiers, thickeners, and stabilizers.
