Spermine dihydrate, also known as SPM-2H2O, is a naturally occurring small molecule that is widely present in organisms including humans. Derived from the amino acid arginine, it serves as a vital constituent of cell membranes. Additionally, spermine dihydrate finds use as a fluorescent probe for imaging purposes and as a stabilizing agent for proteins. Spermine dihydrate is believed to function as a chelating agent, binding to essential metal ions such as calcium, magnesium, and iron. This binding activity plays a role in stabilizing proteins and other molecules within the cell membrane. Furthermore, spermine dihydrate engages in interactions with other molecules like lipids and proteins.
