Application

Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Biochem/physiol Actions

Has activity of the same order of magnitude in organic solvents and water[1].
Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.

Unit Definition

1 U corresponds to the amount of enzyme which liberates 1 μmol oleic acid per minute at pH 8.0 and 40 °C (triolein, Cat. No. 62314, as substrate)

Other Notes

Immobilized lipase with excellent characteristics[2]
