enzyme for starch digestion‚ salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose‚ amylopectin‚ and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency.

Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells.
