Ribose

A water-soluble pentose, also known as d -ribose (see first structural formula), which, together with 2-deoxy- d -ribose, makes up the carbohydrate constituents of nucleic acids, which are found in all living organisms. The universal occurrence of nucleic acids in all living cells makes this pentose highly interesting to biochemists and biologists. The type of nucleic acid that yields d -ribose is referred to as ribonucleic acid (RNA). d -Ribose is a constituent not only of the nucleic acids, but also of several vitamins and coenzymes. As in the nucleic acids, this sugar occurs in the furanose

Ribose

 

a monosaccharide belonging to a group of pentoses (aldopentoses). Ribose exists as optically active D-ribose and L-ribose and as an inactive racemate. Ribose crystals are readily soluble in water. The melting point for D-ribose is 86°–87°C. Ribose characteristically has a high (8.5 percent) acyclic (aldehyde) content in solution. D-ribose is found in all living organisms. It is a component of the most important compounds that effect the transfer of information and energy in cells; these compounds include ribonucleic acids, nucleosides, mononucleotides and dinucleotides. Some coenzymes and bacterial polysaccharides also contain D-ribose.

Long chains of d-ribose are strung together to form ribonucleic acid or RNA, the DNA-like structures essential to copying our genes and translating them into functioning proteins.
D-ribose is natural, quite safe, tastes good (sweet like sugar but healthful-comes as a powder) and is very low in side effects.
"We are proud to add Corvalen D-Ribose to our line of nutraceutical products, enhancing our promise to provide the best and latest supplements on the market," said Doug Lioon, executive chairman.
She follows a healthy supplement program (see table chart below) and relies on D-ribose to give her sustained energy.
The new product line includes: Klean Multivitamin, a twice-daily tablet for promoting overall health; Klean Antioxidants, a superfruit-infused formula to help guard against cellular damage; Klean Cognitive to promote brain health; Klean Probiotic for digestive health; Klean Isolate whey protein; Klean Electrolytes to replenish minerals post-workout; and Klean Endurance, an all-natural D-Ribose supplement for energy.
At the core of metabolic cardiology and so many other great patient comebacks are CoQ10 and three other supplements I collectively call my "awesome foursome." The other three are carnitine, magnesium, and D-ribose. To be sure, I also recommend a high-quality multivitamin and mineral, plus vitamin C, fish oil, and other important nutraceuticals; but these four are my big cardiac weapons.
A natural ingredient for building new ATP, D-ribose is an important component of a "cardiac rejuvenation" regimen.
A prospective, double-blind, randomized, crossover study was conducted to assess the effect of D-ribose supplementation on cardiac function and quality of life in 15 individuals with coronary artery disease and CHF.
