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, [1] which causes the sugar part to be broken off, making the chemical available for use. Many such plant glycosides are used as medications.
Chemical structure of decyl glucoside, a plant-derived glucoside used as a surfactant.. A glucoside is a glycoside that is chemically derived from glucose.Glucosides are common in plants, but rare in animals.
Glycoside hydrolases are classified into EC 3.2.1 as enzymes catalyzing the hydrolysis of O- or S-glycosides. Glycoside hydrolases can also be classified according to the stereochemical outcome of the hydrolysis reaction: thus they can be classified as either retaining or inverting enzymes. [6]
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. [1] Their beneficial medical uses include treatments for congestive heart failure and cardiac arrhythmias ; however, their relative toxicity prevents them ...
Glycosides by glycone type (8 C, 2 P) S. Saponins (25 P) Pages in category "Glycosides" The following 19 pages are in this category, out of 19 total.
Glycoside hydrolases typically can act either on α- or on β-glycosidic bonds, but not on both. This specificity allows researchers to obtain glycosides in high epimeric excess, one example being Wen-Ya Lu's conversion of D-Glucose to Ethyl β-D-glucopyranoside using naturally-derived glucosidase.

To produce steviol glycosides commercially, Stevia rebaudiana plants are dried and subjected to a hot water extraction process. [6]: 56 This crude extract contains about 50% rebaudioside A. The various glycosides are separated and purified via crystallization techniques, typically using ethanol or methanol as solvent. [34]
