Toxicity SummarySafe in the present practices of use and concentration. Ingredient, concentration, and use information are available in documents discoverable at https://cir-reports.cir-safety.org
Natural Pollution SourcesPolysaccharide substance present in cell walls of all plant tissues which functions as intercellular cementing material. One of richest source of pectin is lemon or orange rind which contains about 30% of this polysaccharide.
Human Toxicity ExcerptsPectin bind bile acids, reducing their intestinal reabsorption and promoting their excretion.

Protein BindingPharmacokinetic studies have not been performed as pectin is not absorbed.
Pharmacodynamics · 1건

Pectin increases viscosity and volume of stools which helps it to be used for constipation and diarrhea. It is reported as well to present lowering effects of different body components. This effect depends on the type of pectin which indicated that this effect is related to the composition of the correspondent pectin. Nonetheless, this data is still unclear and more studies need to be performed to conclude this effect of pectin.

Mechanism of Action · 2건

Pectin is an adsorbent that binds to bacteria, toxins and other irritants in the intestinal mucosa. Pectin is able to decrease the pH in the intestinal lumen and provides a soothing effect on the irritated mucosa.

IN WIDE VARIETY OF TRIALS (SWINE, CHICKENS, RABBITS, RATS & MAN) ORAL PECTIN HAD EITHER NO EFFECT OR INCR PLASMA CHOLESTEROL IN ABSENCE OF DIETARY CHOLESTEROL, BUT EFFECTIVELY LOWERED PLASMA CHOLESTEROL...IN PRESENCE OF EXOGENOUS CHOLESTEROL BY DECR CHOLESTROL ABSORPTION FROM INTESTINAL TRACT.

Biological Half-LifePharmacokinetic studies have not been performed as pectin is not absorbed.
Metabolism/MetabolitesPectin is depolymerized and de-esterified to a very small extent. It passes to the small intestine as a macromolecule and the majority of the pectin is eliminated unchanged.
