Interactions of pancreatic lipase with bile salts and dodecyl sulfate

Sodium dodecyl sulfate (SDS) binds to pancreatic lipase in a cooperative manner up to about 200 moles/mole of protein. This binding in a rapid and irreversible inactivation of lipase. Bile salts under certain conditions prevent SDS inactivation of lipase when both detergents are present together. Un...
