Concept explainers
(a)
Interpretation:
Whether the molecule acetoacetyl CoA is a C2, C4, C6 or C8 molecule has to be determined.
Concept introduction:
(b)
Interpretation:
Whether the molecule 3-hydroxy-3-methylglutaryl CoA is a C2, C4, C6 or C8 molecule has to be determined.
Concept introduction:
Ketone bodies are water-soluble molecules which are synthesized from acetyl CoA through the process of ketogenesis. Ketogenesis occurs in the mitochondria of the liver cells. The initial reactants are the molecules of acetyl CoA which are produced by the β-oxidation of fatty acid molecules. Ketone bodies are generally produced when the amount of acetyl CoA in the body is much larger than the amount of oxaloacetate. This happens due to the carbohydrate-lipid imbalance in the body caused by much smaller intake of food rich in carbohydrates, or inefficient processing of glucose by the body.
(c)
Interpretation:
Whether the molecule acetoacetate is a C2, C4, C6 or C8 molecule has to be determined.

O Ketone bodies are only formed during times of starvation. Excess acetoacetate produced during ketone body production is mostly exhaled. O Ketone bodies can easily travel from one tissue to another in the body due to the preser Coenzyme A. O Ketone bodies tend to be formed when oxaloacetate concentrations are high. O Ketone bodies can be used as a source of acetyl-CoA in target tissues when blood glucosarrow_forward
