Pancreatic juice contains: '''Digestive enzymes:''' • ''Protease enzymes'' (such as trypsin) that break down proteins into ''amino acids'' • ''Lipase enzymes'' that break down lipids into ''glycerol'' & ''fatty acids'' • ''Amylase'' an enzyme that breaks down carbohydrates into ''sugars'' '''Bicarbonate ions:''' • ''Bicarbonate ions'' neutralise the hydrochloric acid in chyme that enters the duodenum ensuring the pH of the duodenum is around This is essential for the function of pancreatic enzymes. The pancreas also secretes hormones such as insulin that play a very important role in regulating blood-sugar levels. Many diabetics must take insulin injections in order to help regulate their blood sugar level.
