Description

General description

Lipases belong to the class of hydrolases. Microbes of plant and animal basis mainly produce lipase enzyme. It can also be produced by marine organisms.[1]

Application

Lipase from wheat germ has been used:

• to prepare enzyme solution for the biodegradability test[2]
• to treat diacetates of Mep-Xylp, to generate monoacetylated xylosides[3]
• to test its efficacy in selenium speciation analysis and to determine the contribution that impurities could make to Se determination in real samples[4]

Biochem/physiol Actions

Lipases are used in detergent, food, leather, pharmaceutical and dairy industries.[1] It has several characteristics like substrate specificity, stereospecificity and regioselectivity. It also participates in various bioconversion reactions like, hydrolysis, esterification, acidolysis and aminolysis.[5]

Tri-, di-, and monoglycerides are hydrolyzed (in decreasing order of rate).

Quality

Contains acid phosphatase.

Unit Definition

One unit will hydrolyze 1.0 microequivalent of fatty acid from a triglyceride in 1 hr at pH 7.4 at 37 °C. (This is equivalent to approx. 10 microliters of CO₂ in 30 minutes.)

Preparation Note

Prepared essentially by method of Singer, T.P., J. Biol. Chem., 174, 11 (1948).
