The Smallest Drugs There sure are a lot of carboxylic acids and phenols, and a lot more sulfur than we're used to seeing. And pretty much everything is polar, very polar, which makes sense: if you're down in this fragment-sized space, you've got to be making some strong interactions with biological targets. These are fragments that are also drugs, so fragment-based drug discovery people may find this interesting as the bedrock layer of the whole field.

Amino Acids: biologically important organic compounds made from amine (NH2) & carboxylic acid (COOH) functional groups along with a side-chain specific to each one; key elements are C, H, O, N w/ other elements in side-chains; about 500 known aa's
