glutamine

[boxfishpooalot]

Hey Randy and all,

Im dosing glutamine powder at the rate of 1 gram a day. Its components are L-Glutamine and N-Acetly L-Glutamine.

I have also been dosing vodka. When I dosed only vodka I saw a reduction in Nitrate and Phosphate. Both eventually were .01ppm Po4(hanna) and undetectable No3 via api.

However, after dosing with glutamine for about a week, my nitrate has climbed to about 20ppm. While phosphate remains a constant .01ppm.

Is the No3 from the glutamine? I noticed its chemical forumula is C5H10N2O3 .

What spurred this addition?

yes glutamine contains two (-NH2) - amino groups, which in excess these nitrogen sources could get converted to ammonia and ultimately nitrate.

I have to add my voice to the question why? Glutamine is not an amino acid. It may be metabolized to glutamic acid (an amino acid) through bacteria action, releasing ammonia that may later end up as nitrate.

glutamine actually IS an amino acid, but that's besides the point here. why are you dosing glutamine?

 

[jdoenumber2]

This should be an intresting debate. Go at it boys.

Greetings All !


While I would designate L-glutamine as an amino acid if asked, it is perhaps worth noting that it might also be fairly viewed as being the amide of glutamic acid. Once you start viewing things at the metabolic level of scleractinian coral behavior, this is not an insignificant distinction. Anyway ...


For those wanting to investigate the context of why folks might want to dose L-glutamine, this one is the classic that arguably started the whole amino acid dosing in marine aquaria discussion ball rolling ...

So there is no real reason to put an amino acid in aquariums? What about the levels of the amino being present in frozen foods? I am guessing your "friends" at probido are selling this product?

Bottom line is that there is no testing for said amino acids or complexes of said amine(s). So bascally you are encouraging the "blind"dosing regimine of amino acids as well as other orgainc compounds that may or may not be exceptionally detrimental.

Google search results cary as much weight as wikipedia.

My old phone friend from many years ago when she was working on her Ph.D. @ RSMAS.. She told me she was going to some eastern U as a post Doctorate to study ammino-acid receptors in fish. It looks like she might be at Myriad Genetics Inc, Salt Lake city Utah.

The amount of glutamine being dosed by boxfish is probably much greater than what you would encounter by dosing amino acids (AAs) via one of those supplements reefers commonly use. Thus, the observation of higher nitrate levels could be explained by breakdown of excess glutamine which could fuel production of nitrates. Of all the AAs, glutamine is likely to contribute most to nitrates since it is more "nitrogenous" and we know about how it can be metabolized. Of course, the higher nitrates could have nothing to do with glutamine per se, but an explanation was asked for so we are speculating...

A jargon stickler, huh? It is lots of things by chemical name, and could be called an amino acid. But it is not a required amino acid.

In any case, if you want to dose amino acids, I'd stick to aspartic and and/or glutamic acid.

not trying to be a stickler , but as someone who is trained in biochemistry we were always taught that glutamine (Q) is one of the 20 naturally occurring amino acids. so i wanted to clarify in case someone had thought it was an amino acid.

 

[Randy Holmes-Farley]

OK, my mistake, I'll concede I should not have stated it wasn't an amino acid.

thanks guys. I used vodka only and nitrates dropped to about 5ppm. I expect 0 again within a few days of vodka only.
