Common Name | Rebaudioside A |
---|
Description | Rebaudioside A belongs to the class of organic compounds known as steviol glycosides. These are prenol lipids containing a carbohydrate moiety glycosidically linked to a steviol (a diterpenoid based on a 13-hydroxykaur-16-en-18-oic acid) moiety. Steviol glycosides are the chemical compounds responsible for the sweet taste of the leaves of the South American plant Stevia rebaudiana (Asteraceae), which is a member of the sunflower family native to Paraguay and Brazil. Steviol glycosides are the main ingredients (or precursors) of many sweeteners marketed under the generic name stevia and several other trade names. Stevia is widely used as a non-nutritive replacement for common sugar (sucrose). Rebaudioside A is one of the major sweetening constituents of commercial stevia. Stevia leaves typically contain 9.1% stevioside and 3.8% rebaudioside A (by dry weight) as the two major sweeteners (PMID: 19961353 ). Rebaudioside A is the sweetest and most stable steviol glycoside. Rebaudioside A was first isolated by two French chemists (Bridel and Lavielle) in 1931. A recent evaluation found rebaudoside A to be about 240 times sweeter, and stevioside about 140 times sweeter than sucrose (PMID: 17397883 ). Rebaudioside A also had the least bitterness and aftertaste of all steviol glycosides (PMID: 19961353 ). Rebaudioside A binds to the T1R2 and T1R3 (sweet) receptors as well as the T2R4 and T2R14 (bitter) receptors (PMID: 24705770 ). Rebaudioside A is not an endogenously occurring human metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Rebaudioside A is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults or impacts from environmental, dietary and occupational sources. |
