[1] It is also manufactured industrially by BASF (in Ludwigshafen, Germany) and by Kuraray (in Asia) as an intermediate to pharmaceuticals and aroma compounds.
They also play a major role in protecting cellular membranes, stabilising cell proteins and supporting the body's immune system.
Prenol is polymerized by dehydration reactions; when there are at least five isoprene units (n in the above formula is greater than or equal to five), the polymer is called a polyprenol.
They are important in the acylation of proteins, carotenoids, and fat-soluble vitamins A, E and K. Polyprenols also play a vital role in cell metabolism.
The pharmacological activity of polyprenols is based on their substitutive effect in the case of dolichol deficits which are observed with chronic inflammatory, degenerative and oncological diseases.
