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.. Debalina. . Mukhopadhyay. . . Containing carbon, hydrogen, nitrogen, oxygen. .

Proline differs from other amino acids in that its side chain and amino N form a rigid, five -member red ring structure (Figure 5). Proline, then, has a secondary (rather than a primary) amino group.
