Is exogenous lanosterol a micronutrient?

P Boldrini

    Physiological Chemistry and Physics
    |January 1, 1981
    PubMed
    Summary

    Dietary lanosterol, a cholesterol precursor found in immature animal flesh, can form insoluble compounds in the body. Avoiding this exogenous lanosterol through diet adjustment is recommended to prevent potential health disorders.

    Area of Science:

    • Biochemistry
    • Human Physiology
    • Nutritional Science

    Background:

    • Lanosterol is a key cholesterol precursor present in the human diet.
    • Dietary lanosterol can accumulate in the body at concentrations exceeding its solubility limit.
    • Immature animal flesh is a significant dietary source of lanosterol.

    Purpose of the Study:

    • To investigate the physiological implications of dietary lanosterol.
    • To identify the formation of insoluble lanosterol-cholestanol-water adjuncts (CL-2W).
    • To recommend dietary strategies for managing exogenous lanosterol intake.

    Main Methods:

    • Analysis of dietary components, specifically lanosterol content in animal flesh.
    • Observation of lanosterol interactions with cholestanol and water in physiological conditions.
    • Assessment of potential health risks associated with CL-2W formation.

    Main Results:

    • Lanosterol from the diet can form an insoluble adjunct, CL-2W, with cholestanol and water.
    • This insoluble compound formation occurs at concentrations exceeding lanosterol's solubility.
    • CL-2W is implicated as a potential contributor to various health disorders.

    Conclusions:

    • Exogenous lanosterol intake through diet should be minimized.
    • Dietary adjustments are necessary to avoid the accumulation of insoluble lanosterol compounds.
    • Reducing dietary lanosterol may mitigate risks associated with CL-2W related disorders.
