General description
Application
Lipase from porcine pancreas has been used:
- in lipase inhibition assay with plant extracts[3]
- in in vitro digestion gelatinized starch/fiber mixtures[4]
- with simulated intestinal fluid to mimic the digestive tract condition of by L. fermentum PC1 in fermented oats[5]
Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.
Biochem/physiol Actions
Lipase from porcine pancreas (PPL) catalyzes the hydrolysis of fats (lipids). It plays an essential role in the digestion, transport, and processing of dietary lipids (e.g. triglycerides, fats, oils) in most living organisms.[2] PPL is cost-effective and is useful in biotransformation reactions.[1] It displays high selectivity, and catalytic activity.[1] PPL is also used in the detergent formulation for removing oil stains from clothes.[1]
Lipases catalyze the hydrolysis of esters in aqueous solutions and the synthesis of esters in non-aqueous solutions. They also produce hydroxyl and carboxylic groups through the hydrolysis of ester linkages in poly(ethylene terephthalate).
Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.
Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.
Unit Definition
One unit will hydrolyze 1.0 microequivalent of fatty acid from a triglyceride in 1 hr at pH 7.7 at 37 °C using olive oil.

Nanocrystalline lanthanum hexaboride (LaB(6)) films have been deposited on molybdenum foil by the pulsed laser deposition (PLD) technique. The as-deposited films were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The XRD pattern shows
