General Description

Potassium Lactate is the potassium salt of lactic acid, serving dual functions as a potassium source and as a precursor for bicarbonate generation through hepatic metabolism via the Cori cycle.

Mechanism of Action

Potassium Lactate dissociates into potassium ions that restore intracellular cation balance essential for nerve conduction and cardiac function, while lactate is metabolized to bicarbonate, correcting metabolic acidosis.

Application

Used in the management of electrolyte and acid-base disorders. Potassium Lactate is indicated for hypokalemia with metabolic acidosis, electrolyte depletion, and as a component of balanced resuscitation solutions.

The molecular mechanisms behind lactate's piezo-protective effect on Listeria monocytogenes were investigated using transcriptomic analysis. Exposure of the pathogen to 2.8 percent potassium lactate promoted a shift in its central metabolism, favoring the metabolism of propanediol and ethanolamine together with the synthesis of the B12 cofactor. This metabolic shift suggests the activation of the methyl cycle, which would promote modifications in membrane properties, resulting in an enhanced resistance of the pathogen to high-pressure processing. The study provides insights on the mechanisms developed by L. monocytogenes in response to lactate and/or high-pressure processing and sheds light on the understanding of this piezo-protective effect.

What advantage does Potassium Lactate offer over potassium chloride?

Potassium Lactate provides concurrent correction of both potassium deficiency and metabolic acidosis, as lactate is metabolized to bicarbonate.

What storage conditions are required?

Store at room temperature in a tightly sealed container, protected from light and moisture.

What purity grade is available?

It is supplied as a high-purity grade suitable for R&D and pharmaceutical manufacturing.

Can packaging and order quantities be customized?

Yes, both packaging formats and order quantities can be tailored to meet specific R&D and production needs.
