Digestion of carbohydrate

As we well know that carbohydrate is being the primary source of energy for us. Our brain & Muscles primary fuel is glucose. brain not will be able to function properly if an adequate amount of glucose in not present in our body. Our muscles fuel store "glycogen"is formed by glucose only which helps in contracting  and relaxing the muscles. Glucose is being the simplest form of carbs . Each and every carbohydrate's end product is glucose after undergoing several breakdown processes.

         When person eats the carbohydrates it will be digested by different enzymes and then absorbed into the blood stream through various mechanism . When a person eat a carbohydrates then suddenly its digestion starts as the mouth contain the enzymes (salivary - alpha amylase ) which start breaking the carbohydrates into smaller sugar i.e polysaccharides, sucrose, lactose ,maltose etc This will continues in stomach and small intestine where a bile released by liver , HCL in stomach & pancreatic juice released by pancreas into small intestine help to breakdown carbohydrates  into smallest form glucose in order for it to be absorbed into the blood stream through the intestinal lining. 

         The carbohydrates are broken down to its smallest form which is being the simple sugar and absorbed into the blood stream. once the glucose is entered into the blood it can be distributed throughout the rest of the body . Blood distribute the nutrients from the point of absorption throughout the body or wherever it is required. 

           As soon as the glucose enters the blood stream through the intestine the serum glucose level will rise and result in hyperglycaemia(a state of high blood sugar ). The hyperglycaemia will continues to increase after every meal if the body doesn't do something to bring the serum glucose level down again.

              Thus hyperglycaemia will results after every carbohydrate containing meal. Our body respond to this change in serum glucose level by excreting a hormone known as insulin into the blood stream .The main function of insulin is to utilise the available glucose. Insulin being an intrinsic hormone & it is also known as anabolic hormone. This is a very important function of insulin as it help body to store energy in the form of glycogen & fat for later use if needed.  

              Thus by this process the carbohydrate digestion gets completed which either result in glycogen or fat.
