Synonyms: Ammonium formate
Formic acid ammonium is the ammonium salt form of formic acid, which is an endogenous metabolite. Formic acid ammonium activates the nitric oxide/cyclic guanosine monophosphate (NO/cGMP) signaling pathway in endothelial cells and inhibits calcium ion influx in vascular smooth muscle cells, resulting in vasomotor relaxation. Formic acid ammonium inhibits cytochrome C oxidase (CcO) and disrupts the electron transport chain, leading to ATP depletion. Formic acid ammonium can be used as a feed additive, which can lower the feed pH value, inhibit the growth of microorganisms (such as Escherichia coli, Salmonella), and extend the shelf life of the feed .
