Unlike glucose, which is metabolized broadly and under tight hormonal control, the majority of ingested fructose follows a distinct pathway, primarily in the liver. This process allows it to bypass major regulatory checkpoints that govern glucose metabolism, leading to significant differences in its metabolic fate.

In humans, tracer studies show that ingested fructose can be oxidized faster than glucose, with up to 59% of a fructose load being oxidized within a few hours. This rapid rate is due to significant biochemical differences between how the body processes the two seemingly similar monosaccharides.

According to scientific research, the liver primarily metabolizes fructose due to a unique enzymatic pathway, unlike glucose, which can be utilized by almost any cell in the body. The answer to why does the liver prefer fructose lies in its distinct biochemical processing, which has significant implications for overall health, especially regarding fat production and metabolic regulation.
