Crossword-Solution: MALTASE 7 letters, 4 clues 🏆 scrabble score: 9

The lactose, maltose, and sucrose are changed through the activity of the lactase, maltase, and invertase into glucose.

When hydrolyzed, either by dilute acids or by maltase, one molecule of maltose yields two molecules of glucose.

But, in every case, the glucoside is easily hydrolyzed by the enzyme _maltase_ (or [alpha]-glucase) if the molecular arrangement is that represented by the [alpha]-attachment, or by the enzyme _emulsin_ (or [beta]-glucase) if the glucoside is of the [beta] type; but emulsin is absolutely without effect upon [alpha]-glucosides, and maltase does not produce the slightest change in [beta]-glucosides.

Furthermore, neither the mannosides, which differ from glucosides only in the arrangement of the H and OH groups attached to one of the asymmetric carbon atoms in the hexose, nor galactosides in which two such arrangements are different (see configuration formulas on page 57), are attacked by either maltase or emulsin.

Again, neither [alpha]- nor [beta]-xylosides, which correspond with the above-described glucosides in every particular except that the HCOH group next the terminal CH_{2}OH group is missing, are hydrolyzed by either emulsin or maltase.
