[{'content': 'Most lipogenic: \nSelect and explain. \nA. Fructose, B. Glucose, C. Galactose, D. Ribose', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Unlike\xa0glucose, ingested fructose is preferentially metabolized by the liver. This and several other features of fructose metabolism make it an exceptionally\xa0lipogenic sugar.\nLipogenesis is increased when sucrose is fed instead of glucose because fructose bypasses the phosphofructokinase control point in glycolysis and floods the lipogenic pathway.\nIncreased dietary intake of fructose significantly elevates the production of acetyl CoA and lipogenes.\nHarper Pg 236, Satyanarayana Pg 279', 'role': 'assistant'}]
