[What is Milk Thistle]

Milk Thistle is a unique herb which contains a natural compound called silymarin. Silymarin nourishes the liver like no other nutrient currently known. The liver acts as the body’s filter constantly cleansing to protect you from toxins.

Over time, these toxins can accumulate in the liver. Milk Thistle’s potent antioxidant properties and rejuvenating actions help keep the liver strong & healthy.

[Function]
1, Toxicology tests showed that:a strong effcets of protecting cell membrane of liver, in Clinical application, Milk Thistle

Extract has good results for the treatment of acute and chronic hepatitis, liver cirrhosis and a variety of toxic liver damage, etc.;
2, Milk Thistle Extract significantly improves the liver function of the patients with symptoms of hepatitis;

3,Clinical applications: for the treatment of acute and chronic hepatitis, cirrhosis, liver poisoning and other diseases.

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.
