Description
Spermine is a naturally occuring polyamine that occurs in all eukaryotes, but is rare in prokaryotes. It is essential for cell growth in both normal and neoplastic tissue. Spermine is formed through the addition of a aminopropyl group to spermidine by spermine synthase. Spermine is strongly basic in character, and in aqueous solution at physiological pH, all of its amino groups will be positively charged.
