How may of the carbon atoms from stearic acid may contribute, through cellular metabolism, to the net synthesis of glucose?

Question

Quizplus · Accepted Answer

Stearic acid is a long-chain fatty acid, and in humans, fatty acids cannot be converted into glucose because humans lack the pathway to convert acetyl-CoA (the breakdown product of fatty acids) into pyruvate or any other gluconeogenic precursors. This is due to the irreversible nature of the pyruvate dehydrogenase reaction that converts pyruvate into acetyl-CoA, making it impossible for acetyl-CoA to serve as a substrate for gluconeogenesis.
