When you mix bromine with another molecule that has a carbon-carbon double bond, the bromine can add across the double bond.
The bromine atoms are very heavy - about 80 times as heavy as a hydrogen atom, or 7 times as heavy as a carbon atom. Bromination usually gives you a molecule that has higher density than the parent molecule.

If you take or are close to someone who takes antidepressant medication, you're probably aware that one class, the SSRIs, is particularly prone to causing sexual side effects. These effects can run the gamut from inhibition of libido, to erectile dysfunction, to a diminished or complete inability to achieve orgasm. It's that last one that we take a look at today - a SSRI went on sale in Britain this week that is touted as inhibiting orgasm - on purpose!

Wow. It's not just anticancer drugs for dogs, there are also "lifestyle" drugs. They think they're people!

Just as the swine flu story was starting to catch all our attention, 21 horses died. It was like plagues were breaking out everywhere! With a couple weeks' hindsight, people are breathing easier about the pig bug (perhaps prematurely), and we know the horses died of selenium toxicity from a supplement.

Let's take a visit back to May 2006. The DJIA was above 11,000 and would continue to increase for more than a year. The Da Vinci Code was in theaters. Don Rumsfeld would continue to look very polished in his tab-collar shirts, but his kung fu would serve him for only six more months, when Bob Gates would replace him, following a mid-term election thumpin'. Americans passed the time by applying for VISA cards which literally allowed them to use their homes as credit cards, with which they would buy granite countertops.
But a specter was haunting America - the specter of H5N1, or "bird flu," which threatened to become a pandemic, just as H1N1, or "swine flu" does today. First, we review a link to a bird-flu era series about antivirals and second, a few good links relating to the present situation.

There are a number of tobacco-associated compounds that are formed by reactions of nicotine. Cotinine is a metabolite formed from nicotine in the body - it hangs around a relatively long time, so it is a good marker for recent nicotine exposure.

Going through emails, I came across a request from ASPEX to link to a scholarship they're offering. $1,000 and "an opportunity to co-author a poster with ASPEX at Pittcon 2010." If you are an undergrad thinking of applying for this, going to Pittcon might be worth more than the $1,000. You couldn't ask for a better analytical chemistry meeting to attend, and this could be a great place to find a job or grad school advisor.
