PROTEINS
Extreme temperatures can denature invertase enzymes, changing their shape and rendering them nonfunctional. Higher temperatures can also disrupt the enzyme-substrate complex, affecting the catalytic activity of invertase. Conversely, lower temperatures can slow down enzymatic reactions by reducing the kinetic energy of molecules, which is necessary for enzyme-substrate interactions.
substrate
For yeast invertase, the cytoplasmic form is 135kDa. The excreted form is 270kDa due to heavy glycosylation
Most of enzymes are pH-dependent. It means that they maintain their correct folding structure only under certain pH levels. If the pH is different, they will either change conformation thus be non-functional (just like if you change structure of USB port in your PC, it won't work either) or certain electrostatic interactions (or H-bonds) required in active place of the enzyme won't be realizable. The same applies for invertase, most probably.
Invertase is commonly obtained commercially from yeast or can be extracted from certain plants, such as honey and figs. It can also be produced by growing yeast in a sugar solution and isolating the enzyme from the yeast cells.

MW of the invertase= 270,000

invertase is used by industries to make the inside of chocolates runny. invertase transforms sucrose in glucose and fructose that is less concistent.

The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
Among the ingredients added (such as sugar) is an enzyme called invertase. The invertase reacts and is what aids in the cordial process, creating the liquid.
