What is Grape Skin extract?

Grape skin extract are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid, and OPCs. Typically, the commercial opportunity of extracting grape seed extract constituents has been for chemicals known as polyphenols, including oligomeric proanthocyanidins recognized as antioxidants.

Grape skin extract is rich in Oligomers Procyanidin Complexes (OPC) , which is a powerful antioxidant. In addition to the ultra rich potence of over 20 times higher than Vitamin C. Grape skin extract is also 50 times better than Vitamin E. Grape skin extract helps to strengthen the immune system, and also slowdown the aging process, which is of very high market value. Procyanidin B2, which is the most active compound to neutralize free radicals that cause aging, is available only in Grape Seed.

In Europe, OPC from grape skin extract proanthocyanidins has been adopted and used for several decades as a safe and effective compound. Grape skin extract has no record of any acute or chronic toxicity, no harmful reaction even under very high dosage. For these reasons, grape skin extract proanthocyanidins has become a new star in the food supplement market.

Muscle fibers, DNA and plastics are all examples of polymers. Watch this video to learn more.

A polymer is a large molecule, or macromolecule, composed of many repeated subunits. Because of their broad range of properties, both synthetic and natural polymers play an essential and ubiquitous role in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass relative to small molecule compounds produces unique physical properties, including toughness, viscoelasticity, and a tendency to form glasses and semicrystalline structures rather than crystals.

The term “polymer” derives from the ancient Greek word πολύς (polus, meaning “many, much”) and μέρος (meros, meaning “parts”), and refers to a molecule whose structure is composed of multiple repeating units, from which originates a characteristic of high relative molecular mass and attendant properties. The units composing polymers derive, actually or conceptually, from molecules of low relative molecular mass. The term was coined in 1833 by Jöns Jacob Berzelius, though with a definition distinct from the modern IUPAC definition. The modern concept of polymers as covalently bonded macromolecular structures was proposed in 1920 by Hermann Staudinger, who spent the next decade finding experimental evidence for this hypothesis.

Polymers are studied in the fields of biophysics and macromolecular science, and polymer science (which includes polymer chemistry and polymer physics). Historically, products arising from the linkage of repeating units by covalent chemical bonds have been the primary focus of polymer science; emerging important areas of the science now focus on non-covalent links. Polyisoprene of latex rubber and the polystyrene of styrofoam are examples of polymeric natural/biological and synthetic polymers, respectively. In biological contexts, essentially all biological macromolecules—i.e., proteins (polyamides), nucleic acids (polynucleotides), and polysaccharides—are purely polymeric, or are composed in large part of polymeric components—e.g., isoprenylated/lipid-modified glycoproteins, where small lipidic molecule and oligosaccharide modifications occur on the polyamide backbone of the protein.
