My August 26, 2020, Email to the FDA and the NIH National Library of Medicine Re: Molecular Formula for Glucose (Blood Sugar) vs. Dextrose (Corn Sugar)

Re: Case CAS-592684-L3B4Z2 - National Library of Medicine Customer Service confirmation TRACKING:000435000512147

Since I discovered that the National Library of Medicine references articles from Wikipedia, this has raised additional questions for factual information regarding pure blood sugar (glucose) vs. dextrose (corn sugar)

I may have discovered a possible false narrative, and I would like to know in what year dextrose (corn sugar manufactured from cornstarch) was first synthesized to be biochemically identical to pure blood sugar (glucose)?  Many publications (including my own blog) quote the same narrative that dextrose (corn sugar) and glucose (blood sugar) are biochemically identical (Molecular Formula C6H12O6).  However, it appears that this may not be factual.

Can you explain why dextrose (corn sugar) has a molecular formula of C6H1407?  This is not the same molecular formula of blood sugar, unless the molecular formula of pure blood sugar (glucose) is also C6H1407.

Dextrose PubChem 66370, Dextrose, Molecular Formula C6H14O7

https://pubchem.ncbi.nlm.nih.gov/compound/66370

Dextrose is corn sugar pursuant to Code of Federal Regulation 21CFR184.1857

https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=184.1857

This refers to corn sugar (dextrose), so you are stating that dextrose (corn sugar) is biochemically identical to dextrose (corn sugar)..

This is not "pure" blood sugar (glucose), but refers to dextrose (corn sugar). so you are stating that dextrose (corn sugar) is biochemically identical to dextrose (corn sugar)..

Question:

What is the actual molecular formula of pure blood sugar (glucose), which is not to be confused with dextrose (corn sugar); e.g., nothing that is designated with the letter "D" (which represents corn sugar, dextrose)? 

Thank you for your assistance.
