There are Dipeptidases which hydrolyze bound pairs of amino acids, called dipeptides. They cleave dipeptides into their two component amino acids. The enzyme just hydrolyze mean add water to the peptide bond.
1. OH -ive from water attack to the NH-CO that is peptide bond to form COOH carrying amino acid
2. Than the H +ive from the water attaches to the NH carrying amino acid to form NH2 group
1) The pancreas as an exocrine gland helps out the digestive system. It secretes pancreatic fluid that contains digestive enzymes that pass to the small intestine as it It lies beneath the stomach and is connected to the small intestine at the duodenum. These enzymes help to further break down the carbohydrates, proteins, and lipids (fats) in the chyme. 2) Pyloric sphincter is located at the base of the stomach and is the contracting ring of muscle which guards the entrance of the to small intestine. It keeps the stomach shut at the far end so that it has a chance to digest proteins, then it opens and allows the contents of the stomach, now called chyme, to pass through the pyloric sphincter and enter the small intestine; the first section is called the duodenum and it does the majority of digestion and some absorption.It controls the emptying of chyme into duodenum. 3) Digestive Function Of The Duodenum The duodenum continues the process of food breakdown. Its name stems from the Latin "duodenum digitorum", meaning twelve fingers or inches. It is roughly horse-shoe-shaped. Anatomically, it is is sub-divided into four segments: the superior, descending, horizontal and ascending duodenum. Inside the duodenal tube, chyme is mixed with fluids from the gallbladder (bile) and pancreas (pancreatic juice). Bile breaks down fat particles into smaller droplets, while pancreatic juice contains enzymes that convert fats into fatty acids and glycerol, plus sodium bicarbonate to neutralize stomach acid. Note: during gastric bypass to reduce severe obesity, the duodenum is bypassed to reduce the amount of nutrients and calories that can be absorbed. Digestive Function Of The Jejunum Roughly 4-7 feet in length, the jejunum is where chemical breakdown of the food chyme is completed. Pancreatic enzymes, along with enzymes produced by the jejunum wall, finalize the food digestion process. The term jejunum stems from the Latin jejunus, meaning empty. Note: in some gastric bypass operations, part of the jejunum is also "bypassed" to reduce calorie intake. Digestive Function Of The Ileum Roughly 7-5 feet in length, the ileum is the final section of the small intestine, linked to the large intestine by the ileocecal valve. The main function of the ileum is to absorb nutrients. Bile is also absorbed here and returns to the liver through blood vessels in the intestinal walls. The unabsorbed watery remains of the food chyme now pass into the large intestine for water-removal and final processing, before being expelled from the body. 4) Digestion Of Protein Protein Digestion In The Stomach Enzymes are crucial contributors to protein digestion. Protein-digesting enzymes are referred to as proteinases or proteases. Protein generally takes the form of very complex molecules arranged in chains of amino acids. So the bonds binding these complex molecules together must first be broken down. This digestive process begins in the stomach, where hydrochloric acid, secreted in the stomach's gastric acid, attacks the protein molecules separating them and breaking them down into amino acids. Then the gastric enzyme pepsin - the only protease able to digest collagen (the fibrous protein found in animal connective tissue) - starts to digest the amino acids. Protein Digestion In The Small Intestine Digestion of proteins continues in the duodenum, the first segment of the small intestine. As in fat digestion, the pancreas helps the process by secreting the pancreatic protease enzymes trypsin and chymotrypsin. Like pepsin, trypsin breaks down a protein into single amino acid molecules, through a process called hydrolysis. During hydrolysis, a water molecule is inserted between the two amino acids which are bonded together. This breaks the bond between them. After breakdown, the amino acids are small enough to pass through the intestinal lining into tiny veins (capillaries) in the villi (the finger-like projections on the wall of the small intestine). Once in the bloodstream, the amino acids are distributed by both red blood cells and by the liquid blood plasma to tissues throughout the body where they are used in the creation and repair of cell structures. Such is the demand for protein, the body maintains a constant balance of amino acids in the blood.

A hydrolysis reaction occurs where H2O is split into H+ and OH-
The H+ is attached to the amide group of one amino acid and the OH- to the carboxyl group of the other.
The link below shows the reaction in the reverse direction where the dipeptide bond is being formed:
