fiber is not digestible
Starch
Simple carbohydrates absorb in the body more easily. They also provide the quickest source of energy to the body. Complex carbohydrates have to breakdown into simple carbohydrates before they can be absorbed by the body.
sugars monosacarids
fiber
Carbohydrates are absorbed by the body and converted into glucose. The glucose can be stored as fat or as glycogen in the liver or the muscles. There is no short term storage of carbohydrates.
fatty acid
monosaccharides
Most of the carbohydrates are absorbed in the small intestine after being digeste. A very small amount are absorbed in the mouth. To find out more about carbohydrates (including the types and classification), see Related Links below
Fats are absorbed in the small intestine, along with carbohydrates and proteins.
Carbohydrates
Carbohydrates are digested until they are mono or disaccharides and then they are absorbed through the intestinal lining.
Carbohydrates are primary used by the body in the form of glucose.Fructose and galactose is also absorbed by the body. But these carbohydrates are not directly utilized as energy by the body, instead they are transported to the liver to be converted into fat or to glucose via the liver's glycogen storage.An answer to your question is therefore hard to give. The body uses carbohydrates in the form of glucose, with the exception of energy storage where the body can use fructose and galactose as well.
Carbohydrates provide instant energy by getting absorbed quickly by the digestive system.
