[What is Epimedium?]

Epimedium extract is a popular aphrodisiac supplement and herbal sexual performance enhancer.It has a long history of traditional use in China for the alleviation of erectile dysfunction and for improving libido and fertility.

Also known as Horny Goat Weed, this supplement supposedly got its name after a farmer noticed that his flock of goats were particularly aroused after eating flowers of a specific type. These Epimedium flowers contain icariin, which is a natural compound that increases blood flow to sexual organs and promotes sex drive. Icariin has been found to increase Nitric Oxide synthesis as well as inhibiting the activity of the PDE-5 enzyme

[Icariin in Epimedium Extract]

Epimedium extracts powder contain an active phytochemical called icariin.Icariin has been observed to exhibit a number of useful traits, including renoprotective (liver protecting) hepatoprotective (kidney protecting), cardioprotective (heart protecting) and neuroprotective (brain protecting) effects.

It is also an antioxidant and can cause vasodilation. It exhibits antimicrobial characteristics and is thought to act as an aphrodisiac.

Icariin is classified as a flavonol glycoside, which is a type of flavonoid. Specifically, icariin is the 8-prenyl derivation of kaempferol 3,7-O-diglucoside, a prevalent and important flavonoid.

[Function]

1. Combat mental and physical fatigue;

2. Induce vasodilation and improve circulation;

3. Lower blood pressure in hypertensive patients;

4. Improve symptoms of erectile dysfunction (ED) through its action as a PDE5  inhibitor;

5. Improve the use of free testosterone in the blood;

6. Increase libido;

7. Alleviate symptoms of depression and stimulate improved cognitive function;

8. Protect against neurological degeneration.

Carbohydrates Lecture II Highlights

1.Linking together of more than one sugar residues creates higher order saccharides. These include disaccharides (two sugars), trisaccharides (three sugars), oligosaccharides (several sugars), and polysaccharides (many sugars).

2. Most of the linkages in higher order saccharides involve glycosidic bonds.

3. Disaccharides include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two glucoses). Linkages of these are shown in the figures in the notes.

4. Sucrose is a non-reducing sugar (has no free anomeric hydroxyl), whereas lactose is a reducing sugar (has a single free anomeric hydroxyl). The sucrose figure in your book shows a confusing structure. You are responsible for the structure of sucrose and the linkages for the disaccharides I described in class.

5. Oligosaccharides are components of glycoproteins.

6. The most common polysaccharides include glycogen (energy storage in animals), cellulose (structural integrity in plants), starch (energy storage in plants), chitin (exoskeleton of insects).

7. Polysaccharides can be homopolymers (contain only one sugar residue) or heteropolymers (contain more than one sugar residue). Homopolymers include glycogen (glucose in alpha 1-4 linkages plus extensive alpha 1-6 branches), cellulose (glucose in beta 1-4 linkages), amylose (glucose in alpha 1-4 linkages), amylopectin (glucose in alpha 1-4 linkages plus some alpha 1-6 branches), and chitin (N-acetyl-D-glucosamine in beta 1-4 linkages).

8. Glycogen is an animal energy storage polysaccharide, amylopectin and amylose combine to form starch, which is a plant energy storage polysaccharide, cellulose is a plant structural polysaccharide, and chitin is a component of insect exoskeletons.

9. The enzyme cellulase is required to digest the beta 1-4 bonds of cellulose. Most animals do not contain cellulase. Ruminants and ungulates contain the bacterium that makes that enzyme.

10. Glycosaminoglycans are polysaccharides that contain either N-acetylgalactosamine or N-acetylglucosamine as one of their monomeric units. They are polyanionic and have interesting chemical properties, as a result. Examples include chondroitin sulfates and keratan sulfates of connective tissue, dermatan sulfates, heparin, hyaluronic acid, and others.

11. Proteoglycans are complexes of proteins and glycosaminoglycans that form feathery structures.
