So the pancreas basically produces its own proteolytic enzymes and it mixes those proteolytic enzymes in a solution that is basic. It consists of bicarbonate. And the reason it's basic is because all the enzymes found in the small intestine only function at a PH that is basic at a PH that is equal to about 8.5. So the pancreas produces proteolytic enzymes that are mixed in a basic solution composed of bicarbonate. Bicarbonate is basically what makes it basic, what gives it a PH of about 8.5. Now, this mixture of bicarbonate and proteolytic enzymes is known as the pancreatic juice.
