Hi Marilyn,
I'm glad you're getting help from Listmembers -- they've always come
through for me, too! And you should be able to get some guidance soon,
from the physicians you'll be seeing this week.

One point I feel I must make clear, though, as it truly impacts the
understanding of how Sinemet works. Your nutritionist has misinformed
you. Protein is not broken down into amino acids in the stomach. Stomach
acids can certainly denature the shape of the protein chain, but the
stomach does not produce any enzymes that will break it into individual
amino acids.   That can only be done by the proteases, which are
released into the small intestine.
That's why the small intestine is the locus of importance in the
interaction between protein and Sinemet.

Best regards to you and your father,
Kathrynne
