Description


Polypodoside C belongs to the class of organic compounds known as steroidal glycosides. These are sterol lipids containing a carbohydrate moiety glycosidically linked to the steroid skeleton. Polypodoside C is an extremely weak basic (essentially neutral) compound (based on its pKa). Polypodoside C is a constituent of the rhizomes of the licorice fern Polypodium glycyrrhiza. It is a natural sweetener. Constituent of the rhizomes of the licorice fern Polypodium glycyrrhiza. Natural sweetener, see above
