一般說明

Research area: Cell Signaling

Lipases are water-soluble, ester hydrolases. Long aliphatic chain acyl esters of cholesterol (cholesteryl esters), triacyl esters of glycerol (triacylglycerols), acyl esters of long chain alcohols (wax esters), diacyl esters of glycerol (diacylglycerols), and monoacyl esters of glycerol, are some of the common substrates for lipases.[1]

應用

脂肪酶在工业上用于拆分手性化合物和生物柴油的酯交换生产。[2]

生化/生理作用

脂肪酶可催化三酰基甘油水解成甘油和游离的脂肪酸。[3]

Deracemizations are clearly preferable to kinetic resolutions in the production of chiral molecules from racemates, as they allow up to 100% chemical and optical yield. Here we present a new process route for multienzymatic deracemizations that is relevant for reaction

Lipolysis is defined as the catabolism of triacylglycerols stored in cellular lipid droplets. Recent discoveries of essential lipolytic enzymes and characterization of numerous regulatory proteins and mechanisms have fundamentally changed our perception of lipolysis and its impact on cellular metabolism.
