The polyamines spermine, spermidine, and putrescine are small organic molecules one or more of which are present in all living organisms. Many natural products contain polyamine residues. Polyamines are synthesized by a highly regulated pathway from arginine or ornithine and also can be transported in and out of cells.

Polyamine Oxidases and Oxidized Polyamines
2021Polyamine oxidases that act at the secondary amino group would be further subdivided according to whether diaminopropane or aminopropionaldehyde were among the products. The highest specific activity was found in the peroxisomal fraction, where its presence has been confirmed histochemically in both rat liver and kidney, although polyamine oxidase was ...

Currently, two major pathways are distinguished along which the polyamines are metabolized: the interconversion pathway and the so-called terminal polyamine catabolism. In vertebrates, the interconversion pathway is a cyclic process which controls polyamine turnover.

Biosynthesis of polyamines and polyamine-containing molecules
Biochemical Journal, 2016Polyamines are evolutionarily ancient polycations derived from amino acids and are pervasive in all domains of life. They are essential for cell growth and proliferation in eukaryotes and are essential, important or dispensable for growth in bacteria.

Recueil des Travaux Chimiques des Pays-Bas, 1936
AbstractThe high boiling amines, obtained by the interaction of 1: 3‐dibromo‐propane and 1: 2‐diamino‐ethane hydrate, have been investigated. The lower terms contain straight chains of dimethylene and trimethylene groups separated by nitrogen atoms but in the higher boiling fractions cyclic amines are present.
