Guest guest Posted December 23, 2001 Report Share Posted December 23, 2001 Hi, I don't quite follow you. First, only some enzymes have the sulfhydrl groups. So these would be the ones getting deactivated by the metals. Why would extra sulfur be a problem? I would think that is you have extra sulfur that would help bing the metals and the enzymes would not have so much competition and would therefore work better. Also, isn't there a major effort to always try to get more sulfur in AS people because of the low levels of natural sulfur? I may be confusing two different things. Why is high sulfur bad? I just found out that ALA contains sulfur. So is this one reason it is such a fabulous chelator, because of the sulfhydryl groups? . Quote Link to comment Share on other sites More sharing options...
Guest guest Posted December 23, 2001 Report Share Posted December 23, 2001 Hi , First, thank you very much for the advice about the magnesium sulfate on the A-M list. I really appreciate it, it will be very helpful. I will probably come back to ask you a few questions if something will not work well Thanks again. About the sulfur and enzymes subject... It's really complicated. Well, it sounds like this for me anyway, and I hope I won't say something wrong. Where is Moria now to help me here? ) Anyway, I will try to tell you what I understood about sulfur and why is not always good while chelation or in general for people who are mercury toxic. No, I will better " give " you what Andy Cutler says about this. It will be way more accurate than I could explain it. ------- The " sulfur " group in these foods is usually a thiol - an SH group stuck onto the carbon backbone of a molecule somewhere. One of these molecules is the amino acid cysteine. Many proteins in your body have cysteine in them. Thus, your body is full of -SH groups that belong to you. If you take something that has one sulfur in it, then that just goes and bumps the mercury off of one of the sulfurs that belong to you. Next time that mercury runs into another sulfur that belongs to you it might stick there. Since chlorella is just a good cysteine source, and all the other " sulfur foods " contribute molecules that have one sulfur in them in the active form, what happens is you make the mercury atoms play pinball among the proteins in your body. They bounce hither and yon - and mercury does its damage when it sticks to a new sulfur group that belongs to you, or comes off of one. Since the " sulfur foods " contribute molecules with one sulfur they don't hold onto the mercury any better than you do, and they greatly increase the amount of damage the mercury does without really removing much of it. Lipoic acid (as dihydrolipoate which your body converts it into), DMSA and DMPS each have TWO thiols per molecule so they hold onto the mercury atoms tighter than your body does and have a chance to really escort the mercury out instead of just stirring it up. Thus these are CHELATING AGENTS - chemicals with 2 or more binding groups per molecule so they hold on to the metal atom tightly. Chlorella, cysteine, penicillamine, glutathione, " sulfur foods, " etc. are not chelating agents in any legitimate chemical sense. --------- So this should tell you why sulfur or cysteine are not always good as chelators or while you chelate or when you are heavy metal toxic. It's about redistribution mainly. Sure, it's good for people low in sulfur because it helps them make more sulfate and glutathion, which are necessary for the body, but only when there is not a sulfur oxidation problem. Sometimes, there are people low in sulfur but who cannot " eat " cysteine or sulfur foods, because their body cannot metabolize it (I suspect it's my son's case). This is why Epsom salt is so good for these kids, because they cannot actually make their own sulfate. As I said, people should check for plasma cysteine. This should give a better idea. High sulfur is not bad. At least I don't think it is. Bad is when you have enough and eat more when you are trying to chelate. Valentina > Hi, I don't quite follow you.

Hi , Okay, I went and found one of Andy's " more technical " posts on this subject. I am quoting from: /message/402 The text below is not the whole post, it is the part that looked relevant to your question, to me. This was written by Andy, and includes quotes of someone else who he is responding to: (sorry about the yucky formatting) ============================================================== << Andy and all, Why should chlorella never be used as a chelator? Also, why should high sulfur foods not be used? >> The " sulfur " group in these foods is usually a thiol - an SH group stuck onto the carbon backbone of a molecule somewhere.
