1. Fluorine in bioorganic chemistry
2. One gas which has been investigated as an analogue of oxygen is fluorine.
3. Right fluorine is the actual element fluoride is the stuff that's in?
4. I would guess that the "something or other" are negatively charged ions of fluorine, chlorine and maybe oxygen.
5. So if you look down your table you've got your concentrations here in parts per million and you can see that everything above fluorine would be a major constituent and everything below it would be a minor constituent.
6. Fish is an excellent source of many important nutrients, including protein (needed for body-building and repair), vitamins (A, B and D) and minerals (calcium, iodine and fluorine).
7. Some elements, such as fluorine and phosphorus, have only one stable isotope, and isotopic substitution cannot be used conveniently to identify vibrations involving them.
8. Other chemicals which pose a threat to stratospheric ozone but whose emissions are smaller include the halon gases (variously containing bromine, chlorine and fluorine) which are used mainly in fire-extinguishers and have an even greater ozone depletion potential (table 6.1); methyl chloroform, which is used as a solvent and cleaning fluid; and carbon tetrachloride, used as a dry-cleaner and to fumigate grain in Eastern Europe (figure 6.3).

12. The first commercially available products from this group of drugs for anti-bacterial chemotherapy were the fluoroquinolones, which bore very little resemblance to the nalidixic acid derivatives that did not contain fluorine.
13. The breakthrough to finding broad spectrum quinolones was made in the early 1980s, when fluorine was substituted at position 6, a piperazinyl residue was introduced at position 7 and new residues were introduced at position 1 of the quinolone basic structure ( 7-;10 ).
