spermides

Spermides are a class of naturally occurring polyamines, characterized by the presence of multiple amine groups within their molecular structure. The most common and well-studied spermides are spermine and spermidine, which are ubiquitous in living cells and play essential roles in various fundamental biological processes.

These compounds are vital for cell growth and proliferation, acting as stabilizers for nucleic acids like DNA and RNA. They are involved in gene expression regulation, influencing processes such as transcription and translation. Furthermore, spermides contribute to the structure and function of ribosomes, the cellular machinery responsible for protein synthesis.

Beyond their roles in nucleic acid and protein metabolism, spermides are implicated in cellular processes like apoptosis (programmed cell death) and autophagy (cellular self-cleaning). They also participate in modulating the immune response and maintaining cellular homeostasis. Due to their widespread importance, spermides have been a subject of considerable research, exploring their involvement in aging, disease, and potential therapeutic applications. Their presence and concentration can vary significantly depending on cell type, metabolic state, and external stimuli.
