Polyuronide is a polymeric substance which consists of uronic acid units that have glycosidic linkages which are commonly combined with monosaccharides. [1]
Polyuronide widely occurs in soil and plants (such as gums and pectic substances). [1]
There are many scientific studies about polyuronide in plants.[ citation needed ] However, the most studied is the presence of polyuronide in avocado and tomato. [2] There is also a study about its occurrence in barrel cactus. [3]
