A part of NH4+ that is formed in the degradation of amino acids is used for the biosynthesis of nitrogen compounds. In most of the land living vertebrates the excess NH4+ is converted in urea and in that form is excreted. In birds and reptiles it is converted into uric acid and in aquatic animals it is directly excreted as urea.. What to Know. What is the Metabolic Fate of Ammonium?.

Phenylketonuria. Phenylketonuria, an inborn error of metabolism inherited as an autosomal recessive trait (the PAH gene is located on chromosome 12q24), is caused by a deficiency or absence of the enzyme needed to metabolize the essential amino acid phenylalanine. Classic PKU is at one end of a spectrum of conditions known as .
