gastric glands
The pancreas produces a variety of enzymes, such as amylase and lipase, as well as an alkaline fluid that helps neutralize stomach acid. These enzymes aid in the digestion of carbohydrates, proteins, and fats in the small intestine. The alkaline fluid also creates a favorable pH environment for the enzymes to function properly.
Carbohydrates
The enzymes and chemicals secreted by the upper end of the small intestine primarily come from the pancreas and liver. The pancreas releases digestive enzymes such as amylase, lipase, and proteases, while the liver produces bile which aids in the digestion and absorption of fats.
The pancreas releases its enzymes into the duodenum, which is the first part of the small intestine.
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.

the duodenum
Acid chyme (nutrient broth from food) enters from the stomach. Protein digesting enzymes enter, but in an inactive form. Pancreatic proteases become activated here. And several digestive enzymes go into the lumen of the duodenum.
Bicarbonate ions secreted by the pancreas neutralize the acidity of the chyme in the duodenum. This helps create a more optimal pH environment for the actions of digestive enzymes in the small intestine.
The pancreas produces pancreatic juices, which contain enzymes that help with digestion. These enzymes are released into the small intestine to break down carbohydrates, proteins, and fats from food.
While the pancreas produces insulin, insulin is a hormone not a digestive enzyme. The enzymes secreted by the pancreas are proteases, lipase, trypsin and amylase.
The pancreas sends enzymes in the alkaline pancreatic juice into the duodenum.
Carbohydrates
Enzymes are produced in various regions of our digestive system. Starch is digested by amylase produced by our salivary glands; protein is broken down by pepsin, manufactured in the stomach. In the upper part of the small intestine - the duodenum - all main nutrient molecules are broken down by enzymes made in our pancreas and by the small intestine itself.
Enzymes from the liver, pancreas and gallbladder are secreted into the small intestine to digest the food inside.
The duodenum is the first part of the intestine; it is the place that the stomach empties it's contents into. Along with that, the duodenum is an essential digestion site. The pancreas, liver and gallbladder all secrete important digestive enzymes into the duodenum. The enzymes digest fats, proteins and fats. Much activity goes on in the duodenum, which is why the duodenum is so crucial for digestion.
