Dear Ecolog-Listers: In one of my courses, we'll discuss nutrition and, inevitably carnivory and herbivory.
Question: Can someone suggest science-based, intelligible web sources that discuss this topic. Background: For years, I have looked into this and the basic story (at least for humans) seems to be that animal food on the average has a fuller complement of aminoacids (particularly the so-called essential ones) than non-animal foods. Yet, thus far, in none of the places consulted, the chemical transformations of some aminoacids into others are addressed. In other words, can the so-called essential aminoacids be produced chemically in the body (or by symbionts) by chemically altering non-essential aminoacids? Clearly, those mechanisms must exist in 100% herbivorous organisms. If you have some constructive suggestions, please email me directly: blayjo...@gmail.com Gratefully, Jorge Jorge A.
