Administration of the fructose analog 2,5-anhydro-d-mannitol (2,5-AM) elicits eating behavior in rats by its action in the liver. To evaluate whether the decrease in liver ATP levels produced by injection of 2,5-AM plays a role in the eating response, we examined the relationship between changes in eating behavior and liver adenine nucleotide levels over time in rats given 2,5-AM. Liver ATP con...
