Studies on human pancreatic lipase
Clinica Chimica Acta, 1966Abstract Samples of pancreatic juice derived from drainage fluid of patients undergoing pancreatic surgery have been fractionated by gel filtration yielding up to three components showing lipolytic activity against emulsified triglyceride. The “fast” (high molecular weight) lipase fraction has been further studied and has been found to be stable for ...

Structure of human pancreatic lipase
Nature, 1990Pancreatic lipase (triacylglycerol acyl hydrolase) fulfills a key function in dietary fat absorption by hydrolysing triglycerides into diglycerides and subsequently into monoglycerides and free fatty acids. We have determined the three-dimensional structure of the human enzyme, a single-chain glycoprotein of 449 amino acids, by X-ray crystallography ...

Characterization of turkey pancreatic lipase
Biochimie, 2000Turkey pancreatic lipase (TPL) was purified from delipidated pancreases. Pure TPL (glycerol ester hydrolase, EC 3.1.1.3) was obtained after ammonium sulfate fractionation, Sephacryl S-200 gel filtration, anion exchange chromatography (DEAE-Sepharose) and size exclusion column using high performance liquid chromatography system (HPLC).

Purification of hog pancreatic lipase
Archives of Biochemistry and Biophysics, 1959Abstract A technique is described for the purification of hog pancreatic lipase. This technique includes the following steps: aqueous extraction of hog pancreatin, fractional precipitations of the aqueous extract by ammonium sulfate and acetone, differential adsorptions on tricalcium phosphate and aluminum hydroxide, and finally zone electrophoresis ...

Pancreatic lipase-related protein 2 but not classical pancreatic lipase hydrolyzes galactolipids
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1996The pancreatic lipase family contains three subfamilies, the 'classical' lipases and the pancreatic lipase-related proteins 1 (PLRP1) and 2 (PLRP2). Galactolipids are present in membranes of leaves and vegetables and consist of digalactosyldiacylglycerol (DGalDG) monogalactosyldiacylglycerol (MGalDG) and sulfoquinovosyldiacylglycerol (SQDG).

Radioimmunoassay for human pancreatic lipase in acute pancreatitis
Digestive Diseases and Sciences, 1987We examined the utility of serum pancreatic lipase by radioimmunoassay as a diagnostic test for acute pancreatitis and its correlation with serum total amylase, pancreatic isoamylase, and lipase activity. Data were analyzed on 11 patients with documented acute pancreatitis, three groups of patients (N = 104) with nongastrointestinal, gastrointestinal ...

The major sources of vitamin A in the human diet are retinyl esters (mainly retinyl palmitate) and provitamin A carotenoids. It has been shown that classical pancreatic lipase (PL) is involved in the luminal hydrolysis of retinyl palmitate (RP), but it is not known whether pancreatic lipase-related proteins 1 (PLRP1) and 2 (PLRP2), two other lipases ...

Lipase (EC. 3.1.1.3) was isolated from human pancreatic juice and the pancreas tissue to study their physicochemical features. Their molecular weights, optimal pH, optimal temperature, amino acid sequence, secondary structure, inhibitors etc. were investigated.

Although "lipase" contains various lypolytic enzymes, the main object of lipase measurement is pancreatic lipase. Recent advances in pancreatic lipase research clarified its unique structure, and two novel pancreatic proteins, PLRL 1 and 2, were added to the pancreatic lipase gene family.

Substrate specificity of pancreatic lipase
Biochimica et Biophysica Acta (BBA) - Enzymology, 1968Abstract 1. 1. The hydrolysis of esters of oleic acid by pancreatic lipase (glycerol-ester hydrolase, EC 3.1.1.3) depends on the nature of the alcohol. Two factors appear to influence the speed of the reaction: an inductive effect, and steric hindrance. 2. 2.
