Features of Sodium Carbonate




Product name:Sodium Carbonate
CAS:497-19-8
Molecular Formula:Na2CO3
Molecular weight:105.9784 g/mol (anhydrous)
Description of Sodium Carbonate:
Sodium carbonate is a household chemical with a variety of different uses. Its chemical formula, Na2CO3, is similar to that of baking soda, NaHCO3. But baking soda is a nontoxic chemical commonly used in food preparation, while sodium carbonate is toxic. Instead, it's a common cleaning product.
Features:
Sodium carbonate is similar in chemical formula to both baking soda and chalk. It's more basic than baking soda, however, which makes it caustic and potentially harmful if swallowed. It's more water soluble than chalk, which doesn't dissolve well in the body. According to the "CRC Handbook of Chemistry and Physics," it's a crystalline white solid at room temperature, and has a melting point of 1564 degrees Fahrenheit. Sodium carbonate can absorb water from the air, making it decompose at lower temperatures.

Protease Inhibitors (7000u/mg) Exporter




Product name: Protease Inhibitors (7000u/mg)
Description of Protease Inhibitors (7000u/mg):
Protease inhibitor: An agent that can keep a protease from splitting a protein into peptides. Examples of protease inhibitors are saquinavir (brand name: Invirase) and ritonavir (brand name: Norvir), and they are used primarily in HIV/AIDS treatment. They are taken as part of a multi-drug cocktail and have been shown to be capable of significantly reducing the level of HIV virus in the blood. Side effects associated with protease inhibitors include lipodystrophy syndrome, in which the face, arms, and legs become thin due to loss of subcutaneous fat; the skin becomes dry; weight loss occurs; and abnormal deposits of fat occur. Some strains of HIV may be resistant to protease inhibitors.
Protease Inhibitors stop HIV replication by preventing the enzyme protease from cutting the virus into the shorter pieces that it needs to make copies of itself. Incomplete, defective copies are formed which can't infect cells.
Side Effects:Protease inhibitors can cause a syndrome of lipodystrophy, hyperlipidaemia, diabetes mellitus type 2, and kidney stones.

Deoxyribonuclease I(1000u/mg) Supplier



Deoxyribonuclease I (DNase I) is a single, glycosylated polypeptide that degrades unwanted single- and double-stranded DNA. The enzyme works by cleaving DNA into 5' phosphodinucleotide and small oligonucleotide fragments. DNase I is commonly added to cell lysis reagents to remove the viscosity caused by the DNA content in bacterial cell lysates or to remove the DNA templates from RNAs produced by in vitro transcription. Two grades of DNAse are offered, one sufficient for protein work and one that is useful for any application requiring the digestion of DNA in which it is crucial to avoid damage to RNA.

Nice Price for Ursodeoxycholic Acid




Product name:Ursodeoxycholic Acid
CAS:128-13-2
Molecular Formula:C24H40O4
Molecular weight:392.56 g/mol
Description of Ursodeoxycholic Acid:
Ursodeoxycholic acid (UDCA), also known as ursodiol, is a compound produced from bile by the action of intestinal bacteria. Since this bile acid is not produced directly by the body, it is known as a secondary bile acid. One of the functions of bile acids is to act in the intestine to help digest fats and fat-soluble vitamins from food. Ursodeoxycholic acid has been used in pharmacology to dissolve gallstones made of cholesterol, and to treat liver disorders. It has been used for a long time in both human and veterinary medicine.
Melting point:203 °C (397 °F)
