Overview

Quercetin is a type of Flavonol Bioflavonoid found in many fruits, vegetables, leaves, and grains - note that Rutin is a Glycoside of Quercetin.

Quercetin may Enhance the Function of These Substances

Enzymes

 Quercetin may be synergistic with Bromelain. 

 Quercetin may activate Glutathione Peroxidase.  [1]

 Quercetin may increase the activity of Nitric Oxide Synthase (eNOS form).  [2]

 Quercetin may increase the activity of Paraoxonase-1.  [3]

 Quercetin may increase the activity of Tyrosinase.  [4] 

Hormones

 Quercetin may increase the secretion of Adiponectin.  [5]

 Quercetin may enhance the secretion of Insulin.  [6]

Immune System Chemicals

 Quercetin may increase the production of Interferon Gamma.  [7] 

Nucleic Compounds

 Quercetin may protect the body’s endogenous Deoxyribonucleic Acid (DNA) from breakage from Ferric Iron-initiated Hydrogen Peroxide lipid peroxidation (by chelating (removing) Ferric Iron from the body).  Quercetin may inhibit the damage to the body’s DNA caused by Benzpyrene.  [8]

Peptides

 Quercetin may recycle Glutathione.  [9]

Pigments

 Quercetin may increase the production of Melanin.  [10]

Proteins

 Quercetin may increase the production of Cytochrome C.  [11]

Vitamins

 Quercetin may inhibit the oxidation of Vitamin E.  [12] 

Quercetin may Inhibit these Toxic Substances

Amines

 Quercetin may reduce the carcinogenicity of Heterocyclic Aromatic Amines (HAAs) (by interfering with the ability of p450 Enzymes to activate HAAs).  [13]

 Quercetin may reduce the carcinogenicity of Nitrosamines and may inhibit the Nitrosamines-induced Liver damage.  [14]

Electromagnetic Radiation

 Quercetin may inhibit the toxic effects associated with exposure to Gamma-Rays.  [15]

 Quercetin may inhibit the toxic effects associated with exposure to Ultra-Violet Radiation (UV-A form).  [16]

Environmental Toxins

 Quercetin may inhibit the damage to the body’s Deoxyribonucleic Acid (DNA) caused by Benzpyrene and may inhibit the ability of Benzpyrene to cause Cancer.  [17]

 Quercetin may inhibit the ability of Carbon Tetrachloride to damage the Liver.  [18]

Enzymes

 Quercetin may inhibit the excessive release of Acid Hydrolases from Lysosomes.  [19]

 Quercetin may inhibit Aldose Reductase (the enzyme that catalyzes the excessive conversion of Glucose to Sorbitol which is implicated in many of the complications that arise in Diabetes Mellitus).  [20]

 Quercetin may inhibit the activity of Aromatase.  [21]

 Quercetin may inhibit the release of Beta-Glucuronidase from Neutrophils. 

 Quercetin may inhibit the activity of Collagenase.  [22]

 Quercetin may inhibit the activity of Elastase.  [23]

 Quercetin may retard the production of 5-Lipoxygenase.  [24]
