Rebaudioside A and Rebaudioside D bitterness do not covary with Acesulfame K bitterness or polymorphisms in TAS2R9 and TAS2R31. [PDF]

Chemosens Percept, 2013
In order to reduce calories in foods and beverages, the food industry routinely uses non-nutritive sweeteners. Unfortunately, many are synthetically derived, and many consumers have a strong preference for natural sweeteners, irrespective of the safety data on synthetic non-nutritive sweeteners.

Isolation and Structure Elucidation of Rebaudioside D2 from Bioconversion Reaction of Rebaudioside A to Rebaudioside D [PDF]

Natural Product Communications, 2014
We report the isolation and complete structure of an isomer of rebaudioside D, known as rebaudioside D2. This novel steviol glycoside was isolated from a bioconversion reaction of rebaudioside A to rebaudioside D. Rebaudioside D2 possesses a relatively rare 1→6 sugar linkage, which was discovered by extensive analysis of NMR (1H, 13C, COSY, HSQC-DEPT,

A sustainable strategy for biosynthesis of Rebaudioside D using a novel glycosyltransferase of Solanum tuberosum [PDF]

Biotechnology Journal, 2023
Bioconversion of Rebaudioside D faces high-cost obstacles. Herein, a novel glycosyltransferase StUGT converting Rebaudioside A to Rebaudioside D was screened and characterized, which exhibits stronger affinity and substrate specificity for Rebaudioside A than previously reported enzymes.

Discovery of Novel Minor Steviol Glycoside from the Stevia rebaudiana: Structural Characterization and Proposed Biosynthetic Pathway of Rebaudioside D17 [PDF]

Biomolecules
A novel steviol glycoside, Rebaudioside D17, was identified from the leaf extract of Stevia rebaudiana Bertoni. This compound features a rare β-1→4 glycosidic linkage between two glucose units at the C19 position, distinguishing it from its structural ...

Structure–Property Relevance of Two Pairs of Isomeric Steviol Rebaudiosides and the Underlying Mechanism [PDF]

Foods
Although enormous efforts have been made to prepare tasty and soluble steviol glycosides (SGs), the structure–property relationship of SGs still remains unclear, neither in experiment fact nor in the mechanism, such as the influence of linkage type and ...

Safety Assessment on a Modification of Specifications of Rebaudioside D (E960c) to Include Manufacture by Enzymatic Conversion (RP1245) [PDF]

FSA Research and Evidence
The FSA (Food Standards Agency) and FSS (Food Standards Scotland) received an application for the modification of specifications of rebaudioside D (E960c) to include manufacture via enzymatic conversion of a genetically modified production strain of Komagataella phaffi, using the enzymes sucrose synthase and uridine 5’-diphospho(UDP ...

Application of 13C NMR spectroscopy to chemistry of plant glycosides: Rebaudiosides-D and -E, new sweet diterpene-glucosides of Stevia rebaudiana Bertoni.

Chemical and Pharmaceutical Bulletin, 1977
From the leaves of Stevia rebaudiana BERTONI, additional two sweet glucosides, named rebaudiosides-D (4) and -E (5) were isolated. On the basis of 13C NMR evidences as well as the results of chemical and enzymatic hydrolysis, the structures of 4 and 5 were assigned to be β-sophorosyl ester of steviol-13-O-[β-D-glucopyranosyl (1-2)] [β-D-glucopyranosyl-(
