D-Ribose (Cas:50-69-1)

Supplier From China
Sep-24-14

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.

The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
