[What is Tribulus terrestris?]

Tribulus terrestris is a vine that has been used as a general tonic (energy) and herbal treatment for impotence, but is found primarily in dietary supplements marketed for increasing testosterone levels in bodybuilders and power athletes. The idea behind tribulus is that it may increase testosterone levels indirectly by raising blood levels of another hormone, luteinizing hormone.

[Function]

1) Enhance men’s sexual ability.

2) Relieving muscle spasm and cramps;
3) Anti-myocardial ischemia and cerebral ischemia;
4) Relieving stress , regulating blood fat, and reducing cholesterol;
5) Promoting sex gland hormones;
6) Anti-aging and anti cancer;
7) Diuretic, anti-calculus of the urethra, reducing the risk of urinary stone disease and disorder;
8) Promoting muscle growth efficiently, helping the body to be strong and letting muscle to play potential role.

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.
