What are fructose and glucose and how do they differ in terms of their chemical structure and metabolic effects in the body?

Fructose and glucose are both simple sugars, but they differ in their chemical structure and metabolic effects in the body. Glucose is a monosaccharide with a six-carbon structure, while fructose is also a monosaccharide but with a five-carbon structure. Glucose is primarily metabolized in the liver and used for energy production, while fructose is metabolized in the liver and converted into fat. This difference in metabolism can have implications for overall health, as excessive consumption of fructose has been linked to metabolic disorders such as obesity and insulin resistance.
