As nouns the difference between aglycone and glycoside is that aglycone is (organic chemistry) the non-sugar fragment of a glycoside while glycoside is (organic chemistry|biochemistry) a molecule in which a sugar group (the glycone) is bound to a non-sugar group (the corresponding aglycone) by a nitrogen or oxygen atom glycosides yield a sugar after undergoing hydrolysis. ), while the lactone of
