Glycosides are organic compounds formed when a sugar molecule bonds to another molecule, which can be a non-sugar substance like an alcohol or a phenol. This bond occurs through a glycosidic linkage, and the resulting compound can have various biological activities. Glycosides are commonly found in plants and can contribute to their flavor, color, and medicinal properties. In nature, glycosides play important roles in plant defense and signaling. For example, some glycosides, such as saponins and flavonoids, can deter herbivores or attract pollinators. Additionally, certain glycosides are used in traditional medicine and can have therapeutic effects, making them significant in both ecology and pharmacology.
