I will research this some... and let you know what I think. May take me a while as I am extremely busy.
BTW, I was an organismal biology (plants and animals) and ecology double major and had only what chemistry I needed... I am sure there are others on these boards who may serve from the chemistry angle much better than I; though I have found that some chemistry centric folks have a very hard time understanding that chemical reactions do not always occur in the body the same as in a lab.
