dun eat too much medicine lor..take care of yourselves

Once, I asked my lecturer if it is possible to obtain a 100% pure compound in a recrystallization or extraction process. Theoretically, it is possible (theory wad). Experiments shows that it is not possible. Impurities are bound to attach to the compound that we're synthesizing.

When u pop a Panadol the last time you have ache in your head, how would you know that that tablet would do what it was created for? A chemist would know that a single impurities would cost your biological system to malfunction and take your life. So the question is, are your medicines safe?

It is safe lah. Certainly. That's why we need engineers. The engineers will do all the calculation to provide the required condition to produce the medicines. That is why prescribe antidotes are costly. The more expensive, the better. So don't go complaining about your local drug store and accuse them of slashing you up with the exorbitant prices. Cz those drugs are far better than generic ones.

Not easy wor if wanna be a chemist.

You see, I got over 400% yield of an insulin in my previous experiment. That's like so contaminated by other elements and ethanol. How am I suppose to continue my report now? Tell them that they are gonna die when they eat the drug that synthesize by me? Ah nvm, tell them that would reduce the pain.
Die earlier = less pain ma..
lol
