Heisenberg.

Victor: I know every step of this cook.

Walt: Oh, do you?!…

Tell me. Catalytic hydrogenation is protic or aprotic? Because I forgot.

If our reduction is not stereospecific, then how can our product be enantiomerically pure?

I mean, it’s 1-phenyl-1-hydroxy-2-methylaminopropane, containing, of course, chiral centers at carbons number 1 and 2 on a propane chain; then reduction to methamphetamine eliminates which chiral centers again? Because I can’t remember… Come on! Help me out, professor!!

Silly advertisements.

I’ve been thinking for a while, so since I just saw McCains' commercial about how its pizza won't contain certain ingredients that have unfamiliar chemical name to most people, I figured that I should post about it.

Apple, for example, may have a familiar name, but if you read the make up of an apple, you’d see quite a few things baring names that would seem new to you. To understand the relationship between molecules in your food, you need to know university level organic chemistry. We just have to trust that the FDA is doing a good job at evaluating the safety of your food.

For example, I came across an article on wiki about how benzene (one of the most well-known carcinogen) was found in quite a few carbonated drinks. The article states that, under the catalytic presence of heat and light, benzene is produced when benzoic acid (preservative) reacts with ascorbic acid (vitamin c).

There is also the problem with how “organic” is being used to mean something else. Organic, as far as I’m concerned, means that it comes from an organic body. Cyanide is organic; but I wouldn’t sprinkle its salts on my meals.

Food is essentially nutritional and edible chemicals. :)

Chemistry

Ever since I put pennies and matchsticks in a solution of hydrogen peroxide and saw it turn into blue, I’ve been wanting to mix other stuff around. I don’t think it would be too smart though. It’d be wise to calculate the reaction and confirm them before attempting it. I’m still trying to figure out what happened. I suspect copper hydroxide or simply copper ions, but the solution slowly got darker and went from a light greenish-blue to a marine blue after spending the night outside with minimal air exposure (other than the air bottled in).
