What are the end products of nutrient breakdown during digestion?

When we eat something, different processes of digestion begin in our body. These are very complex sequential processes of preparation, breakdown and assimilation of useful organic substances. Proteins are broken down into amino acids during digestion. Fats are broken down into glycerin and fatty acids. Carbohydrates are converted to glucose. To break down some structures into others, special enzymes are needed. A certain enzyme can break down a certain substance to a certain state. That is, carbohydrates with the help of one enzyme cannot be broken down immediately to carbon dioxide and water.
