Exempel på hur man kan använda AGLYCON i en mening

• Intramolecular aglycon delivery, or IAD, a stereospecific glycosylation technique in organic carbohydrate chemistry.
• An aglycone (aglycon or genin) is the chemical compound remaining after the glycosyl group on a glycoside is replaced by a hydrogen atom.
• The aglycon is prepared by enzymatic hydrolysis, since upon acid treatment steviol will undergo Wagner-Meerwein rearrangement to the very stable isosteviol.
• Its function is to catalyse the conjugation of a wide variety of lipophilic aglycon substrates with glucuronic acid, using uridine diphosphate glucuronic acid.
• Gitoformate is a derivative of the glycoside gitoxin, with five of the six free hydroxyl groups formylated, one on the aglycon and four on the sugar.
• The substance is composed of four monosaccharides (glucose, 3-acetyldigitoxose and two digitoxoses) and an aglycon named digoxigenin.
• The general synthesis of Ramoplanin A1, A2 and A3 aglycons entails the preparation of residues 3-9 (heptapeptide 15), pentadepsipeptide 26 (residues 1, 2 and 15–17) along with pentapeptide 34 (residues 10–14), subsequent coupling, and cyclization to create the 49-membered aglycon core of the compound.
• Upon activation of the glycosyl donor group (Y) (usually SR, OAc, or Br group) in the next step, the tethered aglycon traps the developing oxocarbenium ion at C-1, and is transferred from the same face as OH-2, forming the glycosidic bond stereospecifically.
