Human pancreatic lipase: a glycoprotein.
Human lipase has been purified from pancreatic juice. The protein has a molecular weight of 48 000 and an N-terminal residue of lysine. It has been characterized as a glycoprotein containing 4.7 mol of glucosamine, 2.8 mol of mannose, 2.9 mol of fucose, 3.0 mol. of galactose and 1.1 mol of glucose per mol of protein. Two isolipases have been separated by polyacrylamide gel electrophoresis. Their isoelectric points are 5.80 and 5.85, respectively and both are glycoproteins. Immunological cross reactions have been obtained between human lipase and other mammalian lipases (porcine, bovine, ovine, canine and rat).
