Saponin glycosides are found in parts of plants and are used as detergents. Examples include the root of Saponaria officinalis. There are two types of aglycones: steroidal and triterpenoidal. Glycyrrhiza contains glycyrrhizic acid which produces glycyrrhizic acid and two molecules of glucuronic acid upon hydrolysis. It is used as a flavoring agent and for its demulcent, expectorant, and liver-protective properties. Sarsaparilla's active ingredient is sarsaponin which produces sarsapogenin and D-glucose and L-rhamnose upon hydrolysis. It is

Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of inactive glycosides. These can be activated by enzyme hydrolysis, which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications. In animals and humans, poisons are often bound to sugar molecules as part of their elimination from the body.A glycoside is a molecule consisting of a sugar and a non-sugar group, called an aglycone. The sugar group is known as the glycone and can consist of a single sugar group or several sugar groups. The sugars is in its cyclic form and is covalently attached to the aglycon through the hydroxyl group of the hemiactal function.
There are many different kinds of aglycones. It can be a terpene, a flavonoid, a coumarin or practically any other natural occurring product (se figure 1)
The glycone can be attached to the aglycon in many different ways. The most common bridging atom is oxygen (O-glycoside), but it can also be sulphur (S-glycoside), nitrogen (N-glycoside) or carbon (C-glycoside). In general, one distinguishes between α-Glycosides and β-glycosides, depending on the configuration of the hemiactal hydroxyl group. The majority of the naturally occurring glycosides are β-glycosidesGenerally glycosides are more polar than the aglycones and as a result glycoside formation usually increases water solubility. This may allow the producing organism to transport and store the glycoside more efficiently
Many biologically active compounds are glycosides. The pharmacological effects are largely determined by the structure of the aglycone.
Glycosides comprise several important classes of compounds such as hormones, sweeteners, alkaloids, flavonoids and antibiotics

A glycoside is a molecule within which a sugar is absolute to another functional group through a glycoside bond. Glycosides play various vital roles in living organisms. Several plants store chemicals within the kind of inactive glycosides.

A Glycoside is any molecule in which sugar group is bonded through its anomeric carbon to another grp via Glycosidic bond.
A glycosidic bond is a type of chemical bond that joins sugar molecule to another molecule.
The sugar grp is known as glycone and non-sugar grp as aglycone or genin.
The glycone and aglycone portions can be chemically separated by hydrolysis in presence of acid.
The glucose can consist of a single grp or several sugar groups.

Through preventing, diagnosing, and treating illnesses, injuries, and other health-related problems, healthcare refers to the maintenance and enhancement of physical, mental, and social well-being. It includes a variety of services offered by healthcare personnel, such as doctors, nurses, therapists, and other medical experts. In addition to research into new therapies and technology, public health initiatives like immunisation campaigns and disease surveillance are also included in healthcare. Having access to healthcare is regarded as a fundamental human right and is essential to maintaining a populace that is healthy and productive.
