Amylase and Proteases
Fats that are consumed must be broken down in several steps, and the pancreatic digestive enzyme responsible for this process is called pancreatic lipase. Similarly, starches and carbohydrates have to be broken down and are done so by amylase. There are two different types of proteases, trypsin and chymotrypsin. One of the enzymes that is delivered to the intestine as part of pancreatic juices, it aids in the body's absorption of fat. Ad. Amylase is one of the pancreatic digestive enzymes that is not produced only by the pancreas. Also present in saliva, blood and urine, it breaks down the compounds in starch to a usable component. There are a number of types of amylase, and each type breaks down starches at a different point in its structure. The amylase produced by the pancreas is known as alpha-amylase to differentiate it from other types In the human digestive system, the main sites of digestion are the oral cavity, the stomach, and the small intestine. Digestive enzymes are secreted by different exocrine glands including: 1  Salivary glands. 2  Secretory cells in the stomach. 3  Secretory cells in the pancreas.  The pancreas is also a digestive organ, secreting pancreatic juice containing digestive enzymes that assist digestion and absorption of nutrients in the small intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme. There are several types of pancreatic cancer, involving both the endocrine and exocrine tissue. Pancreatic adenocarcinoma, which affects the exocrine part of the pancreas, is by far the most common form. The many types of pancreatic endocrine tumors are all uncommon or rare, and have varied outlooks. Types of pancreatic cancer. There are two types of pancreatic cancer, that of the exocrine gland and that of the endocrine gland. About 95 percent of pancreatic cancers begin in the exocrine (enzyme-producing) cells of the pancreas. 1  Exocrine tumors: Most tumors affecting the exocrine gland are called adenocarcinomas. 2  Endocrine tumors: These tumors are less common and are most often benign. 1 Exocrine tumors: Most tumors affecting the exocrine gland are called adenocarcinomas. 2  This type of cancer forms in the pancreas ducts. 3  Treatment for these tumors is based on stage of growth. 4 It is then released into the ductules which empty the contents into the pancreatic duct. These chemical catalysts are inactive until it enters the lumen of the small intestine, where it is activated by the acidity of the stomach contents or other digestive enzymes. Various enzymes act on different types of food. There are three pancreatic enzymes for the digestion of proteins within the food in the small intestine. These type of enzymes are known as proteases. 1  Trypsin. 2  Chymotrypsin. 3  Carboxypolypeptidase. 4  Elastase. There are two very important things to know about neoplasms of the pancreas. First, some, such as the intraductal papillary mucinous neoplasm, are curable precancerous lesions. Just as colon cancer arises from curable precancerous colon polyps, so to do some pancreatic cancers arise from curable precancerous lesions.  In pancreatitis, enzymes of the exocrine pancreas damage the structure and tissue of the pancreas. Detection of some of these enzymes, such as amylase and lipase in the blood, along with symptoms and findings on X-ray, are often used to indicate that a person has pancreatitis. There are several types of pancreatic cancer, involving both the endocrine and exocrine tissue. Pancreatic adenocarcinoma, which affects the exocrine part of the pancreas, is by far the most common form. The many types of pancreatic endocrine tumors are all uncommon or rare, and have varied outlooks. The pancreas is made up of five types of islet cells, which manufacture hormones such as insulin. First, there are the major beta cells, which are 65 to 80 percent of islet cells in the pancreas (which manufacture hormones). These produce insulin-the hormone that helps the body store and use glucose.
