Aglycone

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.
Research.
A way to identify aglycone is proposed to extract it from Agave spp. by using H-NMR and Heteronuclear multiple bond correlation (HMBC) experiments. The HMBC experiment can be combined with other techniques such as mass spectrometry to further examine the structure and the function of aglycone.
A study on molecular markers in human aortic endothelial cells published that aglycone stoped cell migration but not monocyte adhesion, which is the initial step of atherosclerotic plaque formation.
