Detection and determination of lipase (acylglycerol hydrolase) activity from various sources

Abstract: Methods for the detection and determination of lipases (acylglycerol hydrolases) and preparation of assays are reviewed including substrates, conditions and screening. Some newer methods for the determination of lipase activity are discussed. Several of these are: (a) titrimetry, (b) colorimetry of Cu soaps of free fatty acids (FFA), (c) colorimetry of chromophores in the acyl chain of FFA or in glycerol, (d) radioassay, (e) gas liquid chromatography, (f) enzymatic treatment of FFA and measurement of the resul… Show more

“…Phenolphthalein indicator of 2-3 drops was added to each of the reaction mixture with respect to different crude lipase enzymes of isolates and the control. The contents of each reaction mixture were titrated with 0.05M NaOH solution to an end point of pink color at pH 10.0 [17,18]. Lipase activity was calculated as micro moles of free fatty acids formed from olive oil per ml of crude lipase enzyme [11] as per equation (2).…”

“…Com relação à especificidade, a literatura relata que é controlada pelas propriedades moleculares da enzima, estrutura do substrato e por fatores que afetam a ligação enzima-substrato. 40 As lipases podem ser classificadas de acordo com sua especificidade posicional (não específicas ou 1,3-específicas) ou quanto à especificidade por ácidos graxos 35,36 (Tabela 2). Além disso, lipases podem apresentar especificidade estereoquímica, atuando particularmente sobre um isômero óptico.…”
