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.
This quiz covers the process of energy production through the citric acid cycle, involving keto acid and amino acid uptake by cells or organelles.
