Explain the process of digestion of following :ProteinCarbohydrates Lipids |
| Answer» Carbohydrate : Carbohydrates are your body\'s preferred energy source and are found in the forms of starch, sugar and fiber. Digestion begins in your mouth where the process of chewing mechanically breaks food into small pieces. Enzymes in the saliva initiate chemical digestion. When you swallow, partially digested carbs travel down your esophagus to the stomach with little additional digestion. From there, carbohydrates move into the small intestine where enzymes released by the pancreas break them into simple forms to be absorbed into the bloodstream. Fiber is indigestible and passes through your gastrointestinal tract without being broken down.Lipid: Most lipids that you consume in your diet are fats. Some digestion occurs in your mouth and the stomach, but most takes place in the small intestine. Bile is produced by your liver, stored and released in your gall bladder and emulsifies fat globules into smaller droplets. This greatly increases the surface area that allows lipase, a fat-digesting pancreatic enzyme, to aid in digestion.Protein: Protein is found in meat, eggs, dairy products, fish, nuts and beans. Before your body can use protein to build and repair tissues, the large molecules of protein must be digested by enzymes into small molecules called amino acids. Digestion of protein begins in your stomach with the aid of gastric juices. Through the action of a group of potent enzymes from the intestinal lining and the pancreas, digestion continues in the small intestine. From there, amino acids are absorbed into the bloodstream and transported throughout your body. | |
