Earth's tilt

That's logical, but not the case, for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.

In our bodies, enzymes in our saliva and pancreas hydrolyse polysaccarides like starch and dissacharides (sucrose) to produce gl

Stolb23 [73]

Explanation:

The enzymatic digestion of starch by amylase can be performed in the laboratory by several ways. But below there is an example of it

In order to have the best protein performance we have to set the temperature of the reaction to 37 celsius degrees.

Prepare a starch solution and spread into tubes
Prepare an amylase solution and spread into tubes
Adjust the pH to the optimum range with buffers, that is about 6.7 to 7.
Adjust the temperature of the tubes reaction to 37 celsius degrees.

The wrong temperature and the pH can unfold the enzymes and make the binding site inefficient.

Pipette the starch solution in the tubes with enzymes.

By the final step the glucose will be produced by the enzymatic digestion of amylase.

It's attached the scheme of the hydrolyzation of a starch strain
