Brief Introduction

Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin. People use quercetin as a medicine.

Quercetin is used for treating conditions of the heart and blood vessels including “hardening of the arteries” (atherosclerosis), high cholesterol, heart disease, and circulation problems. It is also used for diabetes, cataracts, hay fever, peptic ulcer, schizophrenia, inflammation, asthma, gout, viral infections, chronic fatigue syndrome (CFS), preventing cancer, and for treating chronic infections of the prostate. Quercetin is also used to increase endurance and improve athletic performance.

Main Function

1.Quercetin may expel phlegm and arrest coughing, it can also be used as anti-asthmatic.

2. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors.

3.Quercetin may inhibit histamine release from basophils and mast cells.

4. Quercetin may control the spread of certain viruses within the body.

5, Quercetin may help reduce tissue destruction.

6.Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

In this video, I introduce the topic of carbohydrates / sugars.

(CH2O)n is the general formula for a monosaccharide or simple sugar. Glucose (C6H12O6) is a very common and very important example.

Carbohydrate names end in “-ose”
Aldoses have aldehydes in their straight-chain forms (depicted as Fischer projections)
Ketones have ketones in their straight-chain forms (depicted as Fischer projections)

There are D sugars and L sugars, and the convention is based on the Fischer projections of D-glyceraldehyde and L-glyceraldehyde. The two are enantiomers because they are opposite in absolute configuration at all of their chiral centers (which, in this case, is only one). D-glyceraldehyde has an OH on the right, while L-glyceraldehyde has an OH on the left. Sugars that have their last OH on the right are D sugars; sugars that have their last OH are L sugars. Most sugars that exist in life forms are D sugars.

In the video, I depict the difference between Fischer projections (straight chain sugars) and Haworth projections (sugars in their ring forms). I also briefly mention the idea of anomers as a class of epimers, which are a specific class of diastereomers.

Diastereomers are stereoisomers that differ in at least one, but not all chiral centers.
Epimers are stereoisomers that differ at only one chiral center (they are a subclass of diastereomers).
Anomers are stereoisomers that differ at only one chiral center when that chiral center is specifically the anomeric carbon, the stereocenter that forms when a sugar forms a ring. Anomers are a subclass of epimers.
