General description

Lithium potassium acetyl phosphate is an organometallic compound that is used as a phosphoryl group donor. It is commonly used in protein phosphorylation reactions.

Application

Lithium potassium acetyl phosphate has been used as a component of cocktail A in evaluating the activity of choline acetyltransferase in mice brain tissue homogenates.

Biochem/physiol Actions

Lithium potassium acetyl phosphate is suitable as a source of acetyl phosphate. It is suitable for reducing inorganic monophosphate by-product formation by replacing inorganic oligophosphates in phosphatase-catalyzed transphosphorylation.
