invertase

English

Etymology

From invert +‎ -ase.

Noun

invertase (usually uncountable, plural invertases)

1. (biochemistry, organic chemistry) An enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose (invert sugar), used by bees to produce honey and in the food industry to soften chocolate.
   • 1995, L. F. J. Woods, S. J. Swinton, “8: Enzymes in the starch and sugar industries”, in Gregory A. Tucker, L.F.J. Woods, editors, Enzymes in Food Processing, page 257:

     The costs incurred for the processing of sucrose with invertase could be considerably reduced with the introduction of immobilised invertases, by adopting technology similar to that developed for glucose isomerase.

   • 1997, Karl-Dieter Entian, Hans-Joachim Schüller, “Chapter 13: Genetics of Di- and Trisaccharide Utilization”, in Friedrich K. Zimmermann, Karl-Dieter Entian, editors, Yeast Sugar Metabolism, page 226:

     The disaccharide sucrose and the trisaccharide raffinose are both substrates of invertase. Invertase is encoded by the SUC genes from which six unlinked loci have been identified (SUC1-SUC5, SUC7), which are dipersed through the yeast genome (Lampen, 1968; Ouwehand and van Wijk, 1972; Ottolenghi, 1971).

     Up-regulation of these invertases is a common response to infection (Hall and Williams, 2000).

     The methods used for the immobilization of fungal invertases include adsorption, covalent binding, cross-linking and entrapment (Uzun et al. 2011).

     Nelson and Griffin (1916) reported that invertase was the first enzyme to be immobilized, and it was bound on charcoal and aluminium hydroxide. Subsequently, mant fungal invertases have been immobilized onto a variety of media […] .
