Intestinal glycosidases of three species of seals

Intestinal glycosidases of three species of seals

1. 1. Intestinal glycosidase activities of six individual seals of three different species (Tasmanian and New Zealand fur seals, Southern Elephant seal) were investigated. 2. 2. Pancreatic amylase and intestinal lactase and o-nitro-phenyl- β-galactosidase activities were present at very low levels i...

Zusammenfassung:1. 1. Intestinal glycosidase activities of six individual seals of three different species (Tasmanian and New Zealand fur seals, Southern Elephant seal) were investigated. 2. 2. Pancreatic amylase and intestinal lactase and o-nitro-phenyl- β-galactosidase activities were present at very low levels in all the seals, including a suckling pup. Maltase and isomaltase activities were lower than those of other mammals. Sucrase and trehalase were absent. 3. 3. Seal erythrocyte hexose-1-phosphate uridyltransferase and UDPglucose pyrophosphorylase activities were similar to those of normal human erythrocytes. 4. 4. A sample of Tasmanian fur seal milk was analysed. It was found to contain a trace only of lactose.
