- n. An enzyme capable of effecting the inversion of cane suger, producing invert sugar. It is found in many plants and in the intestines of animals.
- n. By extension, any enzyme which splits cane sugar, milk sugar, lactose, etc., into monosaccharides.
from The Century Dictionary and Cyclopedia
- n. A ferment which inverts higher sugars to lower forms; specifically, a ferment which inverts cane-sugar to dextrose and levulose.

Sorry, no etymologies found.
The bees use an enzyme called invertase to chop it up into the two smaller sugars, one of which, by the way, tastes sweeter than sucrose.
To do so, they must secrete an enzyme called invertase, which breaks sucrose into smaller sugars that the yeast can absorb.
According to the researchers, the GIF1 gene is responsible for controlling the activity of the enzyme invertase, which is located in the rice plant's cell walls and converts sucrose to substances that are then used to create starch.
"The GIF1 gene is responsible for controlling the activity of the enzyme invertase, which is located in the cell wall and converts sucrose to substances that then are used to create starch," said He.
The second counter, called a DNA invertase cascade, works in a similar manner, but is made from genes that code for a protein that both inactivates the original gene and primes the next for activation.
The yeast process (Tompson's), which makes use of the inverting power of one of the enzymes (invertase) contained in ordinary yeast, is interesting.
Mr. H.C. Brill  found raffinase, invertase, casease and protease in the pulp; oxidase, raffinase, casease and emulsinlike enzymes in the fresh bean; and all these six, together with diastase, in the fermented bean.
Soluble enzymes -- proteolytic, diastatic, invertase.
