Carbohydrates are one of the three main macronutrients found in our food, and they play an important role in providing energy for our bodies. Carbohydrates are broken down into simpler sugars, such as glucose and fructose, through the process of digestion, which occurs in the digestive tract.The process of carbohydrate digestion begins in the mouth, where enzymes called salivary amylase start breaking down complex carbohydrates into simpler sugars. This process continues in the stomach, but at a much slower rate due to the low pH environment. Once the food reaches the small intestine, the majority of carbohydrate digestion takes place.The small intestine is lined with villi and microvilli, which are small, finger-like projections that increase the surface area for absorption. Here, enzymes such as pancreatic amylase, sucrase, lactase, and maltase, continue to break down carbohydrates into simpler sugars. These enzymes are secreted by the pancreas and the brush border cells of the small intestine.After digestion, the simpler sugars are absorbed into the bloodstream through the walls of the small intestine. Once in the bloodstream, the glucose is transported to the liver, where it is either stored as glycogen or used for energy by the body's cells. Fructose, on the other hand, is transported to the liver where it is converted into glucose and used for energy.It's important to note that not all carbohydrates are digested and absorbed in the same way. Complex carbohydrates, such as starches, are broken down into simpler sugars through the process of hydrolysis, which involves the addition of water molecules. Simple carbohydrates, on the other hand, such as sugars, are already in their simplest form and do not require further breakdown.In conclusion, carbohydrate digestion is the process by which complex carbohydrates are broken down into simpler sugars through the action of enzymes. This process begins in the mouth and continues in the stomach and small intestine. The majority of carbohydrate digestion occurs in the small intestine, where enzymes such as pancreatic amylase, sucrase, lactase, and maltase, continue to break down carbohydrates into simpler sugars. The simpler sugars are then absorbed into the bloodstream and transported to the liver where they are used for energy.
