s. They are generally glycosylated by a disaccharide
Disaccharide
A disaccharide or biose is the carbohydrate formed when two monosaccharides undergo a condensation reaction which involves the elimination of a small molecule, such as water, from the functional groups only. Like monosaccharides, disaccharides form an aqueous solution when dissolved in water...

- EriodictyolEriodictyolEriodictyol is a bitter-masking flavanone, a flavonoid extracted from Yerba Santa , a plant native to North America...
- HesperetinHesperetinHesperetin is a bioflavonoid and, to be more specific, a flavanone. Hesperidin is water-soluble due to the presence of the sugar part in its structure, so on ingestion it releases its aglycone, i.e, hesperetin....
- HesperidinHesperidinHesperidin is a flavanone glycoside found abundantly in citrus fruits. Its aglycone form is called hesperetin. Its name is derived from the Hesperides nymphs of Greek mythology. Hesperidin is believed to play a role in plant defense. It acts as an antioxidant according to in vitro studies...
- HomoeriodictyolHomoeriodictyolHomoeriodictyol is a bitter-masking flavanone extracted from Herba Santa a plant growing in America.Homoeriodictyol is one of the 4 flavanones identified by Symrise in this plant eliciting taste-modifying property: homoeriodictyol sodium salt, eriodictyol and sterubin...
