Study Notes

Glycosides

  • A glycoside is a compound that consists of a carbohydrate and a non-carbohydrate residue in the same molecule.
  • The non-carbohydrate residue in a glycoside is called an aglycone (nonsugar component).
  • The carbohydrate component in a glycoside is called the glycone (sugar component).
  • The carbohydrate residue is attached to the non-carbohydrate residue through an acetal linkage at carbon atom 1.
