| Abstract: | Lipase-catalyzed acylating reaction of renewable oils for the production of various valuable chemicals has drawn considerable attention in recent years. However, natural raw oil usually contains some phospholipids. Many studies have revealed the remarkable effect of the phospholipids on lipase’s catalytic activity, thermal stability and reaction kinetics. The major phospholipid molecules contained in oils were introduced. The effect of phospholipids on enzyme’s catalytic performance as well as the related influence mechanism was reviewed during the reactions of lipase-mediated hydrolysis, esterification, and transesterification. |
