protein powder + heat

JCVD · 01-04-2008, 08:45 AM

hey guys, this has prolly been asked many times before,

but does heat damage protein powder ?

like if i make pankcakes or something, is the protein less effective ?

thanks

yes it does, at 40 degrees celsius protein starts to denature

It is absolutely no deal whatsoever. You see proteins are long chains of amino acids that are linked together by peptide bonds. Each protein folds into it's own natural 'conformational' shape depending upon the sequence of the amino acids contained within it. Heat and acid will both denature proteins which means they will unfold from this conformational state. However, this does not 'destroy' the protein, it simply causes it to unfold. The amino acids remain intact and are still available. Just to make my point that it does not matter if you denature a protein, look at what happens during digestion. Proteins are exposed to concentrated acid in the stomach (6 Molar Hydrochloric Acid) which will denature almost ANY protein. In the small intestine the denatured protein is then cleaved into individual amino acids, di, and tri-peptides. So as you can see, denaturation is a natural part of digestion and in the end it really doesn't matter anyway if you denature a protein because it ends up being cleaved anyway.

i've wondered about that before (have a thing for hot cocoa). thanks.

OMG R U SERZ?

what about them protein cookies and brownies i made?

does that mean im eating nothing?

technically musclemaniac isnt wrong, the protein does denature, but this just isnt a problem....

well i'm not going to debate with layne, i am wrong in a certain way because the protein does denature, i just thought that denaturing was the same as destroying. sorry for that.
