i may pass out soon due to the headache.

for right now, i need to sort through this mess of information on methionine, cysteine, taurine, glutathione, serine & glycine, at least to start, to try to make sense of what i am and am not getting.

the fruit bowl has 559 mg of methionine and 425 mg of cysteine, which i think should be enough for methionine, cysteine & taurine.

actually, wait. i'm confusing myself, here; if glutathione is a derivative of cysteine, and i'm getting a lot of cysteine, i don't need to worry about synthesizing it from serine - i'm just getting enough cysteine, straight up. yeah. ok. i think i just undid what i was confused about.

see, i had glutathione listed as a derivative of methionine and wanted to make sure i was getting enough methionine to synthesize enough glutathione. but, then i realized i had to convert it to cysteine first, and realized the choke point was serine, not methionine. but, what i should really do is list glutathione as a derivative of cysteine, and then measure the amount of glutathione i need relative to the amount of cysteine i'm getting, making the question of whether i'm getting enough serine to synthesize enough cysteine irrelevant, because i'm just getting enough cysteine flat out.

ok.

that said, when i do serine more formally, the question of conversion to cysteine will come up, and i may base an rdi on how much excess cysteine i may need to produce enough glutathione. 

and, i guess, if i decide i need more cysteine for glutathione production, then i'll need to shift the serine (and glycine) to the methionine row to integrate these things together.

i realize that this is just one pathway in a collection of molecules that have many diverse purposes, but i'm pulling out these molecules because the literature does, and i'm taking cues from experts that have identified the value of them.

this is the reason i write this down - it helps me clarify my thoughts.
