Glycone vs. Aglycone — What's the Difference?

(carbohydrate) The sugar residue of a glycoside.

An aglycone (aglycon or genin) is the compound remaining after the glycosyl group on a glycoside is replaced by a hydrogen atom. For example, the aglycone of a cardiac glycoside would be a steroid molecule.

The nonsugar component of a glycoside that results from hydrolysis of the glycoside.

(organic chemistry) The non-sugar fragment of a glycoside.
