What is Spermine 4HCL 98%?
Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses.


Spermine 4HCL 98% Benefits
Spermine is an endogenous polyamine bearing multiple amino groups. It has been found to play important roles in cellular metabolism in all eukaryotic cells. It also can condense DNA in sperm due to its positive charge in the physiological condition. Because spermine is an endogenous molecule widely present in the biological environment, it is expected that spermine will have better biocompatibility then other synthetic cationic molecules.
