A soluble, nitrogenous ferment, capable of converting starch and dextrin into sugar.

The diastase of the pancreatic juice.

om alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyalin) on starch.

A nitrogenous substance closely resembling diastase, obtained from bran, and possessing the power of converting starch into dextrin, sugar, and lactic acid. Watts.

tute for gum, for sizing, etc., and obtained from starch by the action of heat, acids, or diastase. It is of somewhat variable composition, containing several carbohydrates which change easily to their respective varieties of sugar. It is so named from its rotating the plane of polarization to the right; -- called also…

Pertaining to, or consisting of, diastase; as, diastasic ferment.

Relating to diastase; having the properties of diastase; effecting the conversion of starch into sugar. The influence of acids and alkalies on the diastatic action of saliva. Lauder Brunton.

on from an organized or living ferment; a soluble, or chemical, ferment. Ptyalin, pepsin, diastase, and rennet are good examples of enzymes.

of water, and which causes the substance acted upon to take up a molecule of water. Thus, diastase of malt, ptyalin of saliva, and boiling dilute sulphuric acid all convert starch by hydration into dextrin and sugar. Nearly all of the digestive ferments are hydrolytic in their action.

process by which cane sugar (sucrose), under the action of heat and acids or ferments (as diastase), is broken or split up into grape sugar (dextrose), and fruit sugar (levulose); also, less properly, the process by which starch is converted into grape sugar (dextrose).

The fermentative principle of malt; malt diastase; also, a name given to various medicinal preparations made from or containing malt.

A ferment, resembling diastase, found in mustard seeds.

A disaccharide present in glycosides. Prepared from rutin by hydrolysis with rhamnodiastase. 6-O-a-L-rhamnosyl-D-glucose; C12H22O10.

A ferment resembling diastase, found in bitter almonds. Cf. Amygdalin, and Emulsin.
