  2. Ketone bodies - Wikipedia

    en.wikipedia.org/wiki/Ketone_bodies

    Ketone bodies are water-soluble molecules or compounds that contain the ketone groups produced from fatty acids by the liver (ketogenesis). [1] [2] Ketone bodies are readily transported into tissues outside the liver, where they are converted into acetyl-CoA (acetyl-Coenzyme A) – which then enters the citric acid cycle (Krebs cycle) and is oxidized for energy.

  3. Oxaloacetic acid - Wikipedia

    en.wikipedia.org/wiki/Oxaloacetic_acid

    The reactions related to the urea cycle produce NADH, and NADH can be produced in two different ways. One of these uses oxaloacetate. In the cytosol there are fumarate molecules. Fumarate can be transformed into malate by the actions of the enzyme fumarase. Malate is acted on by malate dehydrogenase to become oxaloacetate, producing a molecule ...

  4. Ketogenesis - Wikipedia

    en.wikipedia.org/wiki/Ketogenesis

    The result is a rate of ketone production higher than the rate of ketone disposal, and a decrease in blood pH. [12] In extreme cases the resulting acetone can be detected in the patient's breath as a faint, sweet odor. There are some health benefits to ketone bodies and ketogenesis as well.

  5. Fatty acid metabolism - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid_metabolism

    The ketones are released by the liver into the blood. All cells with mitochondria can take up ketones from the blood and reconvert them into acetyl-CoA, which can then be used as fuel in their citric acid cycles, as no other tissue can divert its oxaloacetate into the gluconeogenic pathway in the way that this can occur in the liver.

  6. Citrate–malate shuttle - Wikipedia

    en.wikipedia.org/wiki/Citrate–malate_shuttle

    The process occurs in two cellular locations: the cytosol and the mitochondria matrix. A cycle is formed by the system, ensuring that the conversion between acetylene, oxaloacetate, citrate, and malate can continue without the need for foreign molecule addition. It involves six major steps: [1] [8]

  7. Keto acid - Wikipedia

    en.wikipedia.org/wiki/Keto_acid

    In organic chemistry, keto acids or ketoacids (also called oxo acids or oxoacids) are organic compounds that contain a carboxylic acid group (−COOH) and a ketone group (>C=O). [1] In several cases, the keto group is hydrated. The alpha-keto acids are especially important in biology as they are involved in the Krebs citric acid cycle and in ...

    The ketone bodies are released by the liver into the blood. All cells with mitochondria can take ketone bodies up from the blood and reconvert them into acetyl-CoA, which can then be used as fuel in their citric acid cycles, as no other tissue can divert its oxaloacetate into the gluconeogenic pathway in the way that the
