Ribose

Rapid energy repletion for intense exercise

*Over 150 studies demonstrate the ability of ribose, a pentose  sugar found in all living cells, to increase adenosine triphosphate  (ATP) levels and total adenine nucleotide (TAN) recovery, promoting  skeletal and cardiac muscle energy metabolism. Ribose is the  key compound used by the body to form the nucleotides AMP, ADP  and ATP, which are depleted during strenuous physical activity  or from lack of oxygen. Skeletal and cardiac muscle rely on these  metabolites for energy, and two metabolic pathways preserve these  pools. The first mechanism involves salvaging end products of  AMP breakdown, or preventing them from leaving the cell. If they  are salvaged, they may be recycled back to AMP and ultimately  to ATP. The second mechanism for preserving nucleotide pools  is de novo synthesis, or formation of new nucleotides from ribose.  Both of these crucial activities can only begin when ribose is  converted to 5-p
