Re: L-histidine as a chelator?

[Guest guest]

Histidine can't be a chelator, in the sense that it isn't going to be

able to chelate metals out of the body, because Andy refers to

supplementing histidine for various problems and he would have

mentioned something if it could chelate. I don't see anything in the

structure that would make it a chelator:

Some people get confused about terminology.
