A polyamine found in some bacteria; associated with nucleic acids in some viruses; found in human sperm; important in cell and tissue growth; N,N-bis(3-aminopropyl)-1,4-diaminobutane.

spermine

n.
A crystalline polyamine compound, C10H26N4, present in ribosomes and found widely in living tissues along with spermidine, from which it is derived. It was originally isolated from semen.
