Vitamin B12 in HCl production

[H+/K+]

Hey, I'm having trouble finding out the ways in which Vitamin B12 affects the production of hydrochloric acid in the parietal cells. If anyone can explain/point me in the direction of an explaination, I would be greatly appreciative. I know that B12 plays a role in the formation of Red Blood Cells and I know that HCl production requires ions from the blood stream, but is there a direct connection between b12 and HCl? thanks!

 

update: since I wrote the above I did some more research and came across the nuerotransmitter Acetylcholine, which is required in HCl synthesis. Does this ring any bells for anyone? Am I on the right track?

I know that proper amounts of HCl are required in order to get out vitamin B12 from food, but probably this is not what you want to know...
