Glucose and fructose are sugars found in vegetables and fruits, but they are different. Here are a few of them.
Chemical structure
Glucose and fructose have the same chemical formula but their atoms are arranged differently. This structural difference affects how they are metabolised in the body.
Sweetness
Fructose is sweeter than glucose. The use of fructose and glucose is mostly in processed foods and beverages.
Metabolism
Glucose is metabolised in the body through the process of glycolysis. Fructose is primarily metabolised in the liver, where it can be converted into glucose or stored as fat.
Effects on blood sugar
Glucose has a significant impact on blood sugar levels because it is rapidly absorbed into the bloodstream. Fructose has a lower glycemic index and does not cause the same spike,
Absorption
Glucose is absorbed directly into the bloodstream through the small intestine. Fructose is primarily absorbed in the liver, where it undergoes processing before entering the bloodstream.
