D-Ribose Powderとは？用途・使用量・代替品・規格

D-Ribose is a naturally occurring fivecarbon aldose (pentose) belonging to the important category of monosaccharides. It is a key component of ribonucleic acid (RNA) and adenosine triphosphate (ATP) and has wide application value in the global food industry, sports nutrition supplements, pharmaceutical intermediates, and cosmetics. Its molecular formula is C5H10O5, molecular weight is 150.13, CAS number is 50–69–1, EINECS number is 200–059–4, and FEMA number is 3793. D-Ribose appears as a white crystalline powder at room temperature, with a refreshing sweet taste, readily soluble in water, slightly soluble in ethanol, and insoluble in diethyl ether, acetone, and other organic solvents. D-Ribose is naturally present in all living cells and is a key component of RNA and DNA, as well as the sugar backbone of ATP. In the human body, the heart and skeletal muscle have relatively low ATP synthesis rates, making them vulnerable to energy deficits; the availability of D-Ribose directly determines the rate of ATP synthesis in these tissues. Unlike other functional sweeteners or sports supplements, D-Ribose does not merely provide flavor or calories. It directly participates in cellular energy metabolism and is a true energy metabolism regulator. Due to its unique physiological functions, D-Ribose is known as an energy recovery accelerator and heart energy supplement.

D-Ribose is known as the golden molecule for energy metabolism regulation, holding an important position in modern sports nutrition, heart health, and functional foods. Its most outstanding core advantages lie in its unique energy metabolism regulation mechanism, natural safety profile, and wide application adaptability.

Unique ATP Synthesis Acceleration Function: D-Ribose is the sugar backbone of ATP and a precursor for nucleotide synthesis. By being directly converted to ribose5phosphate via ribokinase, DRibose bypasses the complex pathways of glucose metabolism and significantly increases the ATP synthesis rate (by 34 times). Studies show that after ATP depletion due to cardiac ischemia or strenuous exercise, DRibose supplementation restores myocardial ATP levels within 624 hours, whereas traditional pathways require 14 days.
