[What is Black currant?]

The black currant bush is a 6-foot tall perennial that entered the world somewhere in the regions that include northern Asia and central and northern Europe. Its flowers display five reddish-green to brownish petals. The celebrated black currant fruit is a glossy-skinned berry that carries several seeds laden with marvelous nutritional and curative treasures. An established bush can produce ten pounds of fruit per season

Many people enjoy grapes when they are in season, as they are a healthy and nutritious fruit. They’re one of the most easily available fruits, too, and easy to transport and eat, which makes them perfect for lunches. One of the most healthful aspects of these fruits, however, is missing from most of the grocery store varieties, and that is the seed.

Grape seeds have powerful antioxidants known as OPCs, which stands for Oligomeric Proanthocyanidin Complexes. Since it’s less common to find grapes that still contain the seeds in the store, you can get these OPCs and other beneficial compounds in grape seed extract. And you might be interested to know that the American muscadine grape is more powerful than European grapes, and has more health benefits.

The benefits of grape seed extract is primarily antioxidant based. The OPCs in this extract are 20 times greater than is found in Vitamin E, and 50 times greater than in Vitamin C. This type of antioxidant is essential in the formation of collagen, which is the substance that keeps tissues soft and elastic. Collagen is important in vibrant, youthful skin, cell longevity, and flexibility.

Since collagen is so necessary for pain free joint mobility, using grape seed extract can be a way to slow the stiffness associated with arthritis, and can help improve overall flexibility and strength of these joints.

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.
