Andy: why does ALA cross the BBB?

[Guest guest]

To Andy (or anyone else who is up to chemical explanations):

I'm wondering what it is about the BBB and about ALA that

makes it such that ALA crosses the BBB (and other chelators

don't).

It may be that the answer is " we don't know " , that it is

simply an observation that it is so. But, thought you might

have some thoughts on this.

Thank you, always.
