Maastricht University gives me the opportunity to study how chemical differences between individuals affect the metabolism, particularly for humans (I'm a chemist working in biology). Reading biological literature and text books sometimes makes my jaw drop. Biology is beautifully complex and sometimes just doesn't make sense at all.

So, in my WTF-moment of the day, I was reading about various RNA, then nucleotides, etc, and got to cAMP. This, and I know that from WikiPathways too, can act as a secondary signalling compound: membrane receptor passes the signal on to cAMP. But then? I mean, one single molecule. Supposed to give a variety of signals.

A new paper in PeerJ (doi:10.7717/peerj.2322) caught my eye for two reasons. First, it's nice to see a paper using the CDK in PeerJ, one of the journals of an innovative, gold Open Access publishing group. Second, that's what I call a graphical abstract (shown on the right)!

The paper describes a collection of Alzheimer-related QSAR models. It primarily uses fingerprints and the PaDeL-Descriptor software (doi:10.1002/jcc.21707) for it particularly.

My Groovy Cheminformatics with the Chemistry Development Kit book sold more than 100 times via Lulu.com now. An older release can be downloaded as CC-BY from Figshare and was "bought" 39 times. That does not really make a living, but does allow me to financially support CiteULike, for example, where you can find all the references I use in the book.

The content of the book is not unique. The book exists for convenience, it explains things around the APIs, gives tips and tricks.

This blog deals with chemblaics in the broader sense. Chemblaics (pronounced chem-bla-ics) is the science that uses computers to solve problems in chemistry, biochemistry and related fields. The big difference between chemblaics and areas such as chem(o)?informatics, chemometrics, computational chemistry, etc, is that chemblaics only uses open source software, open data, and open standards, making experimental results reproducible and validatable. And this is a big difference!
