Is Polyamine a Polymer?

Polyamine polymer is a polymer, composed of polyamine macromolecules.

How is polyamine made?

Polyamines are synthesized from two amino acids: L-methionine and L-ornithine (an amino acid that is not found in proteins, that is produced as part of the urea cycle). In mammalian cells, putrescine is formed by decarboxylation of ornithine, a reaction catalyzed by the enzyme ornithine decarboxylase (ODC).

What is polyamine spermidine?

Polyamines are polycations that interact with negatively charged molecules such as DNA, RNA and proteins. ... Their levels decline continuously with age and polyamine (spermidine or high-polyamine diet) supplementation increases life span in model organisms. Polyamines have also been involved in stress resistance.
