Description générale

Boric acid is a weak monobasic acid, it accepts OH- ions, hence is a Lewis acid. In boric acid, B is sp2 hybridized, forming a planar triangle structure.The principal oxide of boron, B2O3, is obtained as a vitreous solid by dehydration of boric acid at red heat.

Application

Boric acid can have a large scale use in glass industry as flame retardant, in buffer solutions.
Boric acid finds uses in several areas; such as


  • In glass fibres, to enhance its resistance and color
  • In glazing ceramic wares
  • As a condensing agent, chemical intermediate and as a precursor for preparation of borates and other boron based compounds
  • As a water coolant in nuclear reactors
  • In electrolytic condensers and capacitors 1

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific accumulation

The human solute carrier (SLC26) family of anion transporters consists of 10 members (SLCA1-11, SLCA10 being a pseudogene) that encode membrane proteins containing ~12 transmembrane (TM) segments with putative N-glycosylation sites (-NXS/T-) in extracellular loops and a COOH-terminal cytosolic STAS

The three oncogenes, ErbB receptors, Ras proteins and nucleolin may contribute to malignant transformation. Previously, we demonstrated that nucleolin could bind both Ras protein and ErbB receptors. We also showed that the crosstalk between the three proteins facilitates anchorage independent
