important in the photosynthesis of plant and glucose metabolism of animals and are rarely found accumulated in plants.

Glycosides are compounds that yield one or more sugars among the products of hydrolysis.

The most frequently occurring sugar is

Chemically, the glycosides are acetals. The non-sugar component is known as the aglycone, the sugar component is called the glycone.

One should note that only the ___ forms occur in plants

ould be noted that emulsin and the most other natural enzymes hydrolyze only the beta
varieties.

Glycoside role in the plants

All glycosides are hydrolyzed into sugar and another organic compound by boiling with mineral acids, however , in most cases glycosides hydrolyzed easily by the same plants enzymes in the same tissue but different cells from that contain glycosides

Glycoside contains sugar but still the physical, chemical and therapeutic activity is based on ____ portion

Sugar facilitates the absorption of the glycoside .helping it to reach the site of action

Glycosides are crystalline, amorphous substance which are soluble in water, and dilute alcohol but insoluble in the
