Examples of invertase in a Sentence
Fischer found that the enzyme "invertase," which is present in yeast, attacks methyl-d-glucoside but not methyl-l-glucoside.
That such enzymes are formed in the protoplasm is evident from the behaviour of hyphae, which have been observed to pierce cell-membranes, the chitinous coats of insects, artificial collodion films and layers of wax, &c. That a fungus can secrete more than one enzyme, according to the materials its hyphae have to attack, has been shown by the extraction of diastase, inulase, trehalase, invertase, maltase, raffinase, malizitase, emulsin, trypsin and lipase from Aspergillus by Bourquelot, and similar events occur in other fungi.
We have also used the sensitive potato invertase mini-exon system to systematically mutate the sequence surrounding the branchpoint and the polypyrimidine tract.
The second class include all changes brought about by the agency of enzymes, such as the action of diastase on starch, invertase on cane sugar, glucase on maltose, &c. The actions are essentially hydrolytic.
Ludwigii contain only invertase and not maltase, and therefore ferment cane sugar but not maltose.
