Pectin

Pectin is a structural carbohydrate found in all plants, although some plants have higher amounts of pectin than others. It is classified as a fermentable fiber and prebiotic because animals don't have the enzymes necessary to break it down into simple sugar-bacteria in the hind gut are required to ferment it into fatty acids for energy. Pectin is also classified as a soluble fiber because it attracts water and forms a gel in the digestive tract. This property has many benefits for people and animals such as protecting against gastric ulcers.
