Dolichol, a significant member of the polyprenol family (specifically a type of Polyprenols (13~21) with CAS 308068-00-0), is increasingly recognized for its crucial functions in cellular processes and its potential as a biomarker for aging. This long-chain isoprenoid alcohol plays a vital role in the glycosylation process, which is essential for the synthesis of glycoproteins and glycolipids, fundamental components of cell membranes and key players in cell signaling and recognition.

The primary biological function of dolichol is its involvement in the 'dolichol phosphate pathway'. This pathway is critical for the assembly of oligosaccharide precursors that are subsequently transferred to acceptor proteins, forming glycoproteins. These glycoproteins are vital for various cellular functions, including protein folding, cell-cell adhesion, and immune response. Understanding the intricacies of dolichol as an aging biomarker requires appreciating its role in these fundamental cellular mechanisms.

Researchers are particularly interested in dolichol's correlation with aging. Studies have indicated that dolichol concentration in animal tissues can increase with age, suggesting its potential utility as a biomarker for aging. Furthermore, elevated serum dolichol levels have been associated with the development of chronic cholestatic liver diseases. This connection highlights the diagnostic and prognostic value of monitoring dolichol levels, reinforcing the importance of exploring polyprenols pharmaceutical applications that might modulate these levels.

The insights gained from studying dolichol’s role in cellular processes, such as the synthesis of mannoproteins, are invaluable. This research often relies on the availability of high-purity dolichol and related polyprenols. NINGBO INNO PHARMCHEM CO.,LTD. provides access to these essential research materials, supporting scientists in their investigations into aging, liver diseases, and other metabolic disorders. The ongoing research into polyprenols biological activity continues to uncover new therapeutic targets.

For researchers in gerontology, biochemistry, and pharmacology, understanding the functions of dolichol is paramount. The ability to source reliable Polyprenols (13~21) from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. is critical for advancing our knowledge of aging and developing potential interventions. The continuous exploration of polyprenols in plant metabolism also contributes to a broader understanding of these fascinating compounds.
