Application
Used in the production of confectionary foods and artificial honey.
Biochem/physiol Actions
Invertase hydrolyzes sucrose into glucose and fructose yielding a colorless product, unlike acid hydrolysis which produces colored products.
Other Notes
One unit will hydrolyze 1.0 μmole of sucrose to invert sugar per min at pH 4.5 at 55°C.

Since growth is more sensitive to drought than photosynthesis, trees inhabiting dry regions are expected to exhibit higher carbohydrate storage and less growth than their conspecifics from more humid regions. However, the same pattern can be the result of different

Enzymatic Assay of Invertase
Do pomiaru aktywności inwertazy stosuje się spektrofotometryczny test reakcji zatrzymania przy 410 nm. Jedna jednostka inwertazy hydrolizuje 1,0 μmol sacharozy do cukru inwertowanego na minutę przy pH 4,5 i temperaturze 55 °C.
