The body can make glucose from all fatty acids.
Answer the following statement true (T) or false (F)
False
Typical fatty acids cannot be turned into glucose because those with an even number of carbons-the typical form in the body-break down into acetyl- CoA molecules. Acetyl-CoA can never re-form into pyruvate; the step between pyruvate and acetyl-CoA is irreversible. The options for acetyl-CoA are forming ketones and/or combining with oxaloacetate in the citric acid cycle.
At the end of 1 cycle, no carbons from acetyl-CoA are left to turn into glucose; it is impossible to convert typical fatty acids into glucose.
The glycerol portion of a triglyceride is the part that can become glucose. Glycerol enters the glycolysis pathway and can follow the gluconeogenesis pathway from glyceraldehyde 3-phosphate to glucose. Glucose yield from glycerol is insignificant.
