[What is Rhodiola Rosea]

Rhodiola Rosea (also known as Arctic root or golden root) is a member of the family Crassulaceae, a family of plants native to the arctic regions of Eastern Siberia. Rhodiola rosea is widely distributed  in Arctic and mountainous regions throughout Europe and Asia. It grows at altitudes of 11,000 to 18,000 feet above sea level.

There are numerous animal and test tube studies showing that rhodiola has both a stimulating and a sedating effect on the central nervous system; enhance physical endurance; improves thyroid, thymus, and adrenal function; protects the nervous system, heart and liver; and has antioxidant and anticancer properties.

[Function]

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.
