Pancreatic carboxylester lipase catalyzes the exchange of 18O between water and 13,16-cis,cis-doco-sadienoic acid (DA) in monolayers at the argon-buffer interface (Muderhwa, J.M., Schmid, P.C., and Brockman, H.L. (1992) Biochemistry 31, 141). In mixed monolayers of 18O, 18O-DA and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC)

It has been suggested that at physiological pH, the trypsin-catalyzed activation of the lipase cofactor, procolipase, to colipase has no consequence for intestinal lipolysis and serves primarily to release the N-terminal pentapeptide, enterostatin, a satiety factor (Larsson, A., and C.

Colipase is a cofactor protein which forms a 1:1 complex with pancreatic lipase. This facilitates lipase adsorption to phosphatidylcholine-rich interfaces, presumably as a consequence of the higher affinity of colipase for such interfaces. According to this model, the presence of

Lipase-catalyzed oxygen exchange between 13,16-cis,cis-docosadienoic acid and water in liquid-expanded monolayers with 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine exhibits abrupt, lipid composition-dependent changes in extent and mechanism [e.g., Muderhwa, J. M. and Brockman, H. L. (1992) J. Biol. Chem. 267, 24184-24192]. The critical nature of

The phospholipid fatty acid composition of the North-East Atlantic sponge Polymastia penicillus (South Brittany, France) was investigated. Sixty fatty acids (FA) were identified as methyl esters (FAME) and N-acyl pyrrolidides (NAP) by gas chromatography-mass spectrometry (GC/MS), including eight Delta5,9 unsaturated
