Product name: d-ribose Origin: fermentation method Cas no.: 50-69-1 Molecular formula: c5h10o5 Molecular weight: 150.13 Characteristics: white crystal or crystalline powder, dissoluble in water and very slightly dissoluble in ethanol Physical functions: D-ribose (cas no.: 50-69-1) is the main component of the genetic material¡a¡aribonucleic acid (rna). It also plays a pivotal role in the metabolism of nucleotides, proteins, and fat. D-ribose has very important physiological functions and wide application prospect. As a molecule existing in all cells, d-ribose is the starting molecule for nucleotide and atp synthesis. The molecule itself can also serve as a source for energy. It plays an important role of metabolism in cardiac and skeletal muscles and can accelerate the recovery of the local ischemic and hypoxic tissues. Main physiological functions: -energy increasing -fatigue alleviating -alertness promoting -fat burning Application and dosage: D-ribose is wide used in sport supplement, functional food, energy food, dietary supplement, etc. The maximum daily dosage for oral taking is 60 grams. A single dose less than 10g won¡¡£¤t induce any stomach upset. In addition, as a cosmetic ingredient, d-ribose can be used in cosmetics to promote the skin cell metabolism. This can alleviate and prevent fine lines and wrinkles, boost skin elasticity, and refresh tired-looking skin. The suggested dosage is 0.5-1.5%. Product quality: Aji97 Package and storage: D-ribose is packaged in individually sealed double polyethelene bags within a cardboard drum (25kg). It should be stored in a cool, dry place. The bags should be resealed immediately after use. Chengzhi¡¡£¤s d-ribose has a shelf life of 2 years, when stored properly in its original unopened container.
