I am trying to write an essay on the immunoregulatory properties of chocolate for my 2nd year chemistry project. I have read dozens of papers but time and time again the view point is predominantly biological. What I keep reading are things like "flavonoids act as inhibitors for many pro-inflammatory mediators eg cytokines and eicosanoids", however I cannot find the mechanism by which the inhibit.
I also read some chemical properties such as flavonoids neutralise free radicals, chelate metals like Fe2+ and Cu2+ and that their tricyclic structure determines their anti oxidant properties but I cannot find the effects of these with relation to the immune response.
The essay is not long, only 1000 words including references. Ideally I would like to find the mechanisms by which some of these processes occur. If anyone knew of a good book or a good paper on this and could point me in that direction I would be forever indebted to you!
Many, many thanks in advance
