Optimum temperature for amylase
Did you know?
WebThe optimal temperature of amylase would be 87°C because that’s the degree at which starch was broken down the fastest. Enzymes inside the body are said to function better at the optimal temperature of 37˚C, so the fact that our enzyme functioned better at 87˚C doesn’t support that. WebOptimal activity of alpha amylase of Mw of 45 kDa occurred at 71.5 °C and pH between 5.8 and 6.4, provided it was stabilized by Ca 2 + ions. Otherwise, it was deactivated 442 already at 63 °C.
