Preventing amino death?

[john917v]

I have a plastic jar of protein powder that I keep in my car, so I can stay on track of protein consumption anywhere I may be. I have a question, is this harmful for the aminos in the powder? I know that glutamine is heat-sensitive. I have another container of dextrose/creatine in the car that I mixed at a 5:1 ratio of dextrose to creatine, and it got clumpy, like sand that hardens into 'rocks'

I wouldn't worry too much about the protein. Amino's are pretty hardy and I think the kind of heat that would really do anything would be cooking type heat. Even then it wouldn't destroy them just de-nature them or something...and a lot of the protein you eat on a daily basis is de-natured anyway. I'd keep it in the trunk but I don't think it's a big deal.

The heat is more likely to be a problem for the other components in the protein powder. Depending on what you've got, there could be some fats in there..at least a little and the heat can really speed up the rancidification. And that's not good for you to consume.

But I wouldn't be too concerned about it.
