Gintonin is a glycolipoprotein fraction isolated from Panax ginseng. The non-saponin ingredient was designated as gintonin, where gin was derived from ginseng, ton from the tonic effects of ginseng, and in from protein. The main component of gintonin is a complex of lysophosphatidic acids (LPA) and ginseng proteins such as ginseng major latex-like protein151 (GLP151) and ginseng ribonuclease-like storage protein.[2][3]
GLP151 is a first plant-derived LPA binding protein as one of Bet v 1 superfamily. GLP151 has a LPA binding domain on H147 and H148 at C-terminal. These two histidine residues bind to phosphate group of LPA.[4]
