Hmm, I mean I could say the literal word for chemistry but I don't think that would get what you mean across. That's fine though, translation isn't always about literal translation, it's about *meaning*. "déantús" should work. It means something like "makeup", not makeup you put on your face, more like what your body is made up of.
All that being said, this should work for the second part.
Ní hé mo dhéantús mo nádúr
Wait for more input, especially on the second one I've given you. Someone else might be able to tweak it to make it more eloquent.
