| Application: | Invertase from baker′s yeast (S. cerevisiae) has been used: • in liquid media (YES) and is used to determine the invertase activity • supplemented to the reaction mixture in the extraction and analysis of sugars and starch • for sucrose hydrolysis |
| 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. |
| General description: | Invertase is encoded by the SUC2 (Saccharomyces cerevisiae S288C) gene. In yeast this enzyme exist in: glycosylated (secreted) and non-glycosylated (intracellular) form. The external invertase is composed of carbohydrate (50%) and 60,000 D subunits. |
| Packaging: | 100 mg in poly bottle |
| Unit Definition: | One unit will hydrolyze 1.0 μmole sucrose to glucose and fructose per minute at pH 4.6 at 25 °C. |
