Ammonium Ion (NH₄⁺)

Target
NH₄⁺
Molecular classification
Inorganic ion, Polyatomic ion
01

Overview

The ammonium ion (NH₄⁺) is a polyatomic cation formed by the protonation of ammonia. It plays a crucial role in nitrogen metabolism and acid-base balance in biological systems. While not a direct therapeutic target in the traditional sense, its levels are carefully monitored and managed in conditions like hepatic encephalopathy and urea cycle disorders. Treatments aim to reduce ammonia production or absorption.
