    Study Notes

    Keto Acid and Citric Acid Cycle

    • Keto acid, a product, enters the citric acid cycle to provide energy for life activities.
    • Keto acid can also be converted into other compounds, such as ketoglutaric acid, which is used to synthesize glutamate and enter the urea cycle.

    Amino Acid Transporters and Metabolism

    • Amino acids are taken up by cells or organelles through the participation of amino acid transporters (AATs).
    • Different amino acids rely on specific AATs, but they are not one-to-one matched.
    • Amino acids are structural elements and energy sources of cells, necessary for normal cell growth, differentiation, and function.
    • Amino acid metabolism disorders have been linked to various pathological conditions, including metabolic diseases, cardiovascular diseases, immune diseases, and cancer.

    Protein Abnormalities and Metabolism Disorders

    • Amino acids are the building blocks of proteins and have multiple functions in the body.
    • Metabolism of protein abnormalities can indicate hereditary disorders that affect how proteins are processed in the body.
    • These disorders can result from defects in amino acid breakdown or the body's ability to transport amino acids into cells.
    • Amino acid metabolism disorders are hereditary metabolic disorders that occur when amino acids are not properly processed in the body.
    • Hereditary disorders occur when parents pass on defective genes to their children, causing these disorders.
