In summary, alpha-amylase is an enzyme that breaks down starch into dextrins, which can then be further broken down into glucose. However, temperature plays a crucial role in its effectiveness. As the temperature increases, the enzyme works faster but also risks denaturing and becoming ineffective. The optimal temperature for rapid dextrinization is considered to be 149-153 F (65-67 C), as any temperature above that can denature the enzyme too quickly.

??does anyone know...??

..the maximum temperature a-Amylase can digest starch at? or anything about it? please please please help. i have no clue what I am doing?! :frown:

alpha-amylase turns starch into dextrins - a process sometimes called dextrinization. Dextrins (3-4 glucose molecules bound together) can be further split into glucose by other enzymes.

As temperature goes up two things happen in enzyme reactions:
1. every 10 degrees C increase means the enzyme works approximately
twice as fast.
2. proteins denature with heat - like an egg white hitting a hot frying pan. Egg white is protein. alpha-amylase is a protein. As temperature goes up you risk denaturing amylase, turning it into useless glop. There is a temperature at which the amylase's activity stops because the protein denatures too fast to have any effect. This is also why boiling water kills living things, like many kinds of bacteria, fungi, and yeast.

149-153 F (65-67 C) is usually considered to be the highest temperature for
rapid dextrinization. Higher temperatures, above 67 C, denature the enzyme too fast, the temperature "kills it off" so to speak - before it can do it's job.


Is this what you mean?
