General description

Sodium carbonate (Na2CO3) is an inorganic compound also known as soda ash. It is used in flue gas desulfurization, and in detergent formulations. It is a stronger alkali used as a softening agent in laundry detergents.

Application

Sodium carbonate can be used:
  • A sintering aid with the ZnO (zinc oxide) for the preparation of BaCe0.5Zr0.3Y0.2O3−δ based composite electrolyte material by solid-state reaction.
  • A co-precipitating agent for the synthesis of stable iron oxide nanoparticles from a stoichiometric combination of Fe(II) and Fe(III) salts.
  • A catalyst for the etherification of glycerol to polyglycerols.

Biochem/physiol Actions

Componente amortiguador, puede utilizarse para eliminar las proteínas periféricas de membrana.

Diffuse large B cell lymphoma (DLBCL) is a heterogeneous disease treated with anti-CD20-based immuno-chemotherapy (R-CHOP). We identified that low levels of GAPDH predict a poor response to R-CHOP treatment. Importantly, we demonstrated that GAPDHlow lymphomas use OxPhos metabolism and rely
