General description

Sodium hydroxide, also known as lye and caustic soda, is a strong base used universally as a neutralization agent in the chemical industry, paper making, petroleum refining, cleaning compounds, and drain cleaners.

Application

Sodium hydroxide can be used as:
  • A reagent in the gold-catalyzed selective oxidation of glycerol to glyceric acid.
  • A catalyst for the cross-dehydrogenative coupling of alcohols and hydrosilanes to synthesize silyl ethers.
  • A base in the Sonogashira-type coupling of aryl halides and alkynes to synthesize ynones.

Polyphosphate (polyP) is secreted by activated platelets and has been shown to contribute to thrombosis, suggesting that it could be a novel antithrombotic target. Previously reported polyP inhibitors based on polycationic substances, such as polyethylenimine, polyamidoamine dendrimers, and polymyxin B

A key step in the process of metastasis is the epithelial-to-mesenchymal transition (EMT). We hypothesized that epigenetic mechanisms play a key role in EMT and to test this hypothesis we analyzed global and gene-specific changes in DNA methylation during TGF-β-induced

There is still considerable debate regarding the actual mechanism by which a "cellulase mixture" deconstructs cellulosic materials, with accessibility to the substrate at the microscopic level being one of the major restrictions that limits fast, complete cellulose hydrolysis. In the
