What are Polyvanadates?

What are Polyvanadates?

Filters. (inorganic chemistry) A polymeric form of the orthovanadate anion; and salt containing this anion. noun.

What is the meaning of vanadate?

Vanadate. In chemistry, a vanadate is a compound containing an oxoanion of vanadium generally in its highest oxidation state of +5. The simplest vanadate ion is the tetrahedral, orthovanadate, VO43− anion, which is present in e.g. sodium orthovanadate and in solutions of V2O5 in strong base.

What is vanadate used for?

Vanadate is a good corrosion inhibitor used widely in paint and pigment systems, but there has been little work done to convert Mg alloys with vanadates.

What is kinetic stability?

Kinetic stability, in the context discussed here, is a measure of how rapidly a protein unfolds. A protein can denature irreversibly if the unfolded protein rapidly undergoes some permanent change such as aggregation (egg white) or proteolytic degradation (subtilisin). …

What determines thermodynamic stability?

Thermodynamic stability of compounds can be determined by obviously enthalpy of formation (ΔHf) of individual compounds. The enthalpy of formation will be lesser if the compound is formed from its constituent elements enjoys some greater stability.

How does vanadate inhibit ATPase?

Vanadate inhibits (Na+ + K+)ATPase by blocking a conformational change of the unphosphorylated form.

Is vanadate a complex ion?

In chemistry, a vanadate is an anionic coordination complex of vanadium. anion, which is present in e.g. sodium orthovanadate and in solutions of V2O5 in strong base (pH > 13). …

Does VO3 exist?

Does VO4 exist?

Vanadate(3-) is a vanadium oxoanion that is a trianion with formula VO4 in which the vanadium is in the +5 oxidation state and is attached to four oxygen atoms. It is a trivalent inorganic anion and a vanadium oxoanion. It is a conjugate base of a hydrogenvanadate.

What does kinetically favored mean?

Kinetically favoured reactions are FAST, carried out at LOW Temperatur , does not yield a STABLE product. Thermodynamically favoured reactions are SLOW, requires HEAT , yield a STABLE product.

What does it mean to be kinetically unstable?

The opposite of thermodynamic stability is “kinetic stability”, which describes the reactivity of a system rather than the equilibrium state of that system.
