    Study Notes

    Role of GGT in Liver Health

    • GGT is a liver enzyme involved in the metabolism of amino acids, peptides, and other biomolecules.
    • GGT plays a crucial role in protecting and maintaining liver health by converting glutathione into its constituent amino acids, preventing the build-up of toxic compounds in the liver.
    • This function reduces the risk of liver damage and disease.

    GGT's Functions

    • GGT is involved in the synthesis of lecithin, a phospholipid essential for proper cell membrane function.
    • GGT facilitates the transport of amino acids across cell membranes, necessary for liver tissue growth and repair.

    Clinical Significance

    • Elevated GGT levels in the blood may indicate liver disease or damage.
    • Elevated GGT levels are often associated with alcohol consumption.
    • GGT is not specific to liver disease and can be elevated in other conditions, such as cardiovascular disease and certain cancers.
    • GGT should be evaluated in conjunction with other liver function tests and clinical findings for an accurate diagnosis.

    Overall Importance

    • GGT plays a critical role in maintaining liver health and preventing liver disease.
    • Measuring GGT levels can provide valuable insights into liver function and overall health.
