Polyamines
Amine compounds that consist of carbon chains or rings containing two or more primary amino groups.
Polyamine
D002852
Chromatography, Ion Exchange
Separation technique in which the stationary phase consists of ion exchange resins. The resins contain loosely held small ions that easily exchange places with other small ions of like charge present in solutions washed over the resins.
Organic chemicals which have two amino groups in an aliphatic chain.
Diamine
D013095
Spermidine
A polyamine formed from putrescine. It is found in almost all tissues in association with nucleic acids. It is found as a cation at all pH values, and is thought to help stabilize some membranes and nucleic acid structures. It is a precursor of spermine.
D013096
Spermine
A biogenic polyamine formed from spermidine. It is found in a wide variety of organisms and tissues and is an essential growth factor in some bacteria. It is found as a polycation at all pH values. Spermine is associated with nucleic acids, particularly in viruses, and is thought to stabilize the helical structure.
