Inhibition of amylase activity of human body fluids by citrate

Abstract

Citrate inhibits the amylase activity of blood serum, urine and saliva. Isocitrate, malate, lactate, glycollate, [alpha]-aminoacetate, tartrate, cis-aconitate, glutarate, [beta]-hydroxy-[beta]-methyl-glutarate, tricarballylate and oxalate have no effect on amylase activity. Borate ions activate amylase activity.
