What from are carbohydrates when transported in blood?

Carbohydrates are primarily transported in the blood in the form of glucose. After digestion, carbohydrates are broken down into simple sugars, mainly glucose, which enters the bloodstream. Glucose is then used by cells for energy or stored as glycogen in the liver and muscles for later use. Other simple sugars, such as fructose and galactose, can also be present but are less prevalent than glucose.
