Basically digestive enzymes act on carbohydrates. The monosaccharides or glucose (grape sugar), galactose (milk sugars) and fructose (fruit sugar) are absorbed into your bloodstream unchanged, the disaccharides (double sugars) such as sucrose and lactose have to be broken down into simple sugars first so also do the starches.
The monosaccharides which are principally glucose are absorbed through your intestinal wall and then into your bloodstream to be distributed throughout the body.Certain cells such as brain cells and red blood cells need to have a constant a constant supply of glucose to survive. Some of the glucose gets used immediately by these cells burning it in a series of biochemical reactions to generate energy. The rest of the glucose gets conveyed to your liver, muscles and fat cells where it gets converted into glycogen (animal starch) and fat for storage. when you need more energy that glycogen is converted back to glucose which re-enters your bloodstream for distribution around your body.
Fat cannot be converted to glucose but can be burnt as fuel to conserve glucose. Unlike glucose, galactose and fructose cannot be used directly by your body's cells and therefore must first be converted by your liver to glucose and after that it is also absorbed directly into the bloodstream from your intestine.
Sop when your blood glucose level is high, like after you have eaten a meal, carbohydrate metabolism gets primarily controlled by hormone insulin which restores your glucose level to normal. it does that by stimulating its uptake by the liver, muscles and actipose cells for storage as glycogen and fat. When your blood sugar level is low, such as after exercise, insulin secretion goes down and glucogen stimulates conversion of glycogen to glucose for releasze into the bloodstream. Adrenaline plus corticosteroid hormones produced by your adrenal glands at times of emotional stress act to raise blood sugar levels.

Sugar is a carbohydrate.
The macronutrients of proteins, carbohydrates, and lipids can be metabolized, or broken down, for ATP production within the human body. ATP, which stands for adenosine triphosphate, is the process of converting energy back to its original source, in this case, the human body.

carbohydrates
Cereals contain carbohydrates, which provide the body with an easily metabolized source of energy. Different cereals will also contain fiber, sugar, and various vitamins and minerals as well.
cariogenic
Carbohydrates. Carbs are converted to sugar in the body, and the sugar is the primary energy source. Carbohydrates are the primary components of wheat, corn, potatoes, and some beans. We grind the wheat into flour and bake the flour into bread, so bread, pasta, cake, and any related foods are loaded with carbohydrates. But too much of anything is bad, and excess carbohydrates can be a cause of obesity. Remember, carbs are metabolized into sugar in the body. So you need a balance of carbohydrates and protein (meat, eggs, milk, cheese) to really be healthy.
Sugar is metabolized as a source of energy.
Carbohydrates are essentially sugars - which give the body energy.
Carbohydrates (often called "Carbs" for short) provide the body with a ready source of energy, although other forms of food such as fats and proteins can also be used for this. When absorbed from the gut and metabolized they provide the glucose that cells convert to energy. The greatest consumer of glucose in the body is the brain.
80 % of our body is made up of carbohydrates.
