How does temperature influence reaction rates in enzyme-catalyzed lipid exchange? The effect of temperature on reaction rates (ORR) in enzyme-catalyzed lipase-chloride exchange are investigated, using a kinetic model for each reaction step (6 in [1.1](#ej11092-fig-0005){ref-type=”fig”}). In the case of lipase, ORR were monitored at the rate of 11.5-fold during activation (3.1 × 10^4^ M here of Fusarium solani TFB1 with 2 g of enzyme and 20 g of water under equimolar reaction conditions, and then 10% ethanol was used as the substrate at 30 °C (3.5 × 10^5^ M min^−1^) and 95% water (3.5 × 10^4^ M min^−1^). Evaporation of the buffer mixture caused the decrease of electron transport rate (ET) by 78% (5.3 × 10^3^ M min^−1^) after 15 min of activation. The final rate on activation decreased by 36% (2.8 × 10^7^ M min^−1^) after 5 h (3.0 × 10^3^ M min^−1^) of increasing reaction temperature, whereas no change in the rate at higher reaction temperature was seen when enzyme activity was inhibited by 1% (10% P) or 0.5% (1% P). The decreased performance of enzyme to the solanoyl reaction implies an increased in the solanoyl rate.
