Glycosides are a large group of molecules that generally encompass any molecule that has a sugar bound to a non-sugar molecule (thus separating them from polysaccharides). The sugar (monosaccharide or oligosaccharide) component of the molecule is known as a "glycone", and the non-sugar component is known as the "aglycone" or "genin". Glycosides can be catogorized based on their glycone (glucse glucose vs fructose), type of glycosidic bond (α-glycosides or β-glycosides), or by their aglycone (alcoholic, anthraquinone, coumarin, cyanogenic, flavonoid, phenolic, aponins, steroidal/cardiac, steviol, or thioglycosides). Glycosides play important roles in all living organisms by breaking the bond between the sugar and non-sugar (either with an enzyme or in the presence of acid), and making these products available for certain biological functions <ref>[http://www.newworldencyclopedia.org/entry/Glycoside "Glycoside".
