Glucuronolactone vs D-Glucuronolactone
« on: July 14, 2021, 06:42:26 PM »
is there a difference between Glucuronolactone and D-Glucuronolactone? I see the two terms used online interchangeably, but that might be due to ignorance (not seeing them used interchangeably in a scientific article or such).

I bought some D-Glucuronolactone for some home chemistry experiments which call out for Glucuronolactone...
Yes i know it is used in energy drinks, but my application does not involve anything even close to ingestion, so no worries there.
Any place online that i actually see a chemical formula calls it Glucuronolactone, while term D-Glucuronolactone surfaces in non-scientific discussions about energy drinks and brain fog, so no chemical structure is shown in those pages...

Thanks

Dang, if i only scrolled a bit further down...
Just found a webMD page listing both names:
https://www.webmd.com/vitamins/ai/ingredientmono-1624/glucuronolactone
I guess that answers my question...

Glucose and related molecules can be subdivided into two forms, D and L, which are mirror images of each other.  Generally only one is naturally occurring.  Without a D or an L, the name could refer to either one or to a mixture.  It is ambiguous.  6-phosphoglucono-δ-lactone is an intermediate in the pentose phosphate pathway, but that is a different compound.  I did find one article that had a paragraph of information:

Thank you for additional information.
