To have your blog items show up on this page, use the semantic markup for InChI's and SMILES, using microformats or RDFa. For example, write <span class="chem:smiles">CCCOC<span> instead of just CCCOC, or <span class="chem:inchi">InChI=1/bla<span> instead of InChI=1/bla.

The last Numbers of Atoms post concluded with the assertion that titrations can be used for more than just acid/base determinations. As we’ve discussed, a titration is a procedure in which the concentration of a compound can be determined by reacting...
I have recently caught a cold. In the first days, apart from the sore throat sensation, my nose was totally congested, so I had to use a nasal spray. My option was Olynth. From curiosity at first, I read the list of components of this medicine. Then I thought...

In our last Numbers of Atoms post, we considered volumetric analysis – a simple approach to quantitative analysis that allows for relatively quick determination of the concentration of an analyte in a solution. In a titration,a quantity of reactant (the...

Well after spending last week at a Structure-based Drug Discovery conference that ended up being horribly academic and computational (think force fields and not the cool Star Trek kind), I come back to my blogging pile to find this paper.  In this paper,...

A novel cofactor is not something that is discovered every day, or even every year. So we are lucky this year. The crystal structure of a putative methyltransferase CmoA from Escherichia coli reveals the presence of [(3S)-3-amino-3-carboxypropyl]{[(2S,3S,4R,5R)-5-(6-aminopurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methyl}(carboxymethyl)sulfanium,...

I’ve been performing some internet searches that could cause red flags in the office, but on the other hand it’s a story of citizen science and lab safety. There is a growing trend for people to perform solvent extractions at home, but what they’re...

Earlier this year [1], the crystal structures of human aldosterone synthase (CYP11B2) were solved in complex with a substrate 11-deoxycorticosterone [2] and an inhibitor fadrozole [3]. Strushkevich, N., Gilep, A.A., Shen, L., Arrowsmith, C.H., Edwards, A.M.,...

It looks like someone is using the deadly nerve agent sarin in the ongoing civil war in Syria, which may very well draw the United States into the conflict. I did a project on sarin for a class in my sophomore year of college at NYU. Here is the handout I prepared...

A concerned labmate brought my attention to a chemical abomination on last week’s episode of the increasingly unpopular television show House, M.D.Thanks to a very special friend of mine, we can all enjoy video footage of what Hollywood writers believe...
