Invertase is a glycoprotein that hydrolyses (cleaves) the non-reducing terminal β-fructofuranoside residues. Invertases cleave the O-C(fructose) bond, whereas the sucrases cleave the O-C(glucose) bond. [3] Invertase cleaves the α-1,2-glycosidic bond of sucrose. For industrial use, invertase is usually derived from yeast.
When completed the syrup temperature is raised to inactivate the invertase, but the syrup is concentrated in a vacuum evaporator to preserve color. [ 4 ] Though inverted sugar syrup can be made by heating table sugar in water alone, the reaction can be sped up by adding lemon juice , cream of tartar , or other catalysts , often without changing ...
The enzyme invertase, which occurs more commonly in plants, fungi and bacteria, also hydrolyzes sucrose (and other fructosides) but by a different mechanism: it is a fructosidase, whereas sucrase is a glucosidase.
Moreover, nearly all commercially produced industrial enzymes, such as lipase, invertase and rennet, are made by fermentation with genetically modified microbes. In some cases, production of biomass itself is the objective, as is the case for single-cell proteins, baker's yeast, and starter cultures for lactic acid bacteria used in cheesemaking.

In enzymology, a dextransucrase (EC 2.4.1.5) is an enzyme that catalyzes the chemical reaction. sucrose + (1,6-alpha-D-glucosyl) n D-fructose + (1,6-alpha-D-glucosyl) n+1 Thus, the two substrates of this enzyme are sucrose and (1,6-alpha-D-glucosyl) n, whereas its two products are D-fructose and (1,6-alpha-D-glucosyl) n+1.
