Tryptophan is a routine constituent of most protein-based foods or dietary proteins. It is particularly plentiful in chocolate, oats, dried dates, milk, yogurt, cottage cheese, red meat, eggs, fish, poultry, sesame, chickpeas, almonds, sunflower seeds, pumpkin seeds, spirulina, bananas, and peanuts.nly the L-stereoisomer of tryptophan is used in structural or enzyme proteins, but the R-stereoisomer is occasionally found in naturally produced peptides (for example, the marine venom peptide contryphan).
Tryptophan is a kind of amino acid, which comes from protein. When you eat protein foods (meats, cheese, eggs, birds, etc.), it is broken down into amino acids. They go into your blood stream and try to get into the brain as brain food.Tryptophan is a little runty amino acid.t really should be three meals AND a baked potato three hours after dinner and before you go to bed.
