Types of Organic Formula Back to basics with today’s graphic, with a look at the different ways compounds in organic chemistry can be represented. Obviously, if you’re a chemist, these will all be second nature, but as was quite fairly pointed out with regards to the food chemistry graphics, if you’re not well versed in chemistry, all of those lines and letters might well be a bit perplexing. Here’s a brief explanation of what they mean.
The Smallest Drugs Here is the updated version of the "smallest drugs" collection that I did the other day. Here are the criteria I used: the molecular weight cutoff was set, arbitrarily, at aspirin's 180. I excluded the inhaled anaesthetics, only allowing things that are oils or solids in their form of use. As a small-molecule organic chemist, I only allowed organic compounds - lithium and so on are for another category
