C2C turns 1!

Commitment to Catalysis turns 1 today!

Thanks to everyone who is following. My goal for this next year is to post more frequently--I am aiming for 2-3 times per week. Watch your feed for more updates from the wonderful field of chemical biology and exciting commentary from a graduate student.

Betabrand's Smart Fashion

I'm not usually one to write about clothing or pay much attention to fashion (1). But I will make an exception to discuss San Francisco-based Betabrand. Back in January, Betabrand sent out an open casting call for a photoshoot that would highlight their spring clothing collection. The call specified the company wanted women with advanced degrees or who were working towards advanced degrees. 

Over 60 women Ph.D.s and doctoral candidates responded to the call, including my own classmate, Nicole. 


If you have time, visit Betabrand's website and check out the collection. Even if the clothing is not your style, I think we can all agree that these women are rockstars. 


              
1) In fact, I tend to wear my clothing until it is literally falling apart. 
2) Disclaimer: I am in no way being paid to endorse Betabrand.

Seminar


It's always really fantastic to attend seminar and listen to the amazing research being performed at other institutions. It's even cooler when you and a classmate are able to host the speaker.

Forbes 30 under 30

Congratulations to UCSF student Jon Ostrem (left) and UCSF fellow David Weinberg (right) for being named to Forbes 30 under 30 list in the field of Science!


 

Ostrem, a student in the lab of Kevan Shokat, created mutant-specific inhibitors of the oncogene K-Ras.
Weinberg, a fellow at UCSF,  is studying how cells determine how much protein to produce.

I expect we will continue to hear many awesome things from these two! For the full list, follow This Link.

Chemical Biology vs. Biological Chemistry

"What is chemical biology and how is that different from biochemistry?"

This is the one question I am often asked at family functions, by other students, and sometimes even by other chemists who are not familiar with the discipline. The answer: it’s complicated!

If you search for "chemical biology" on the internet, the results would include hundreds of websites, college syllabi, and opinion pieces, each attempting to describe the field or explain the methodology used by researchers. And while there are some excellent resources about this field, many more results simply describe the idea that chemical biology is “something chemical” associated with “something biological” (1).

Even the experts, those researchers pushing the frontiers of the field, have difficulty nailing down a unified description of what constitutes chemical biology--some arguing that is is the techniques being utilized while others arguing that it is the type of questions being asked. Personally, I like Christopher Walsh's definition: "The goal [of chemical biology] is a seamless application of chemical principles to decipher complexities in biology and bring scientists trained in chemistry to full engagement on biological projects," (2).


This is how I like to simplify the difference:

Adapted from (3). 

Biological Chemistry (aka Biochemistry): The study of the chemical properties of biological systems.
Traditionally, biochemists study biological systems in living organisms. They are interested in the role and function of biological molecules. Common techniques may include enzyme kinetics, mutagenesis, or pharmacology.

Chemical Biology: Manipulating biological systems using the tools/techniques of chemistry.
Conversely, chemical biologists might better be described as engineers. They want to use the tools of chemistry to study or "tweak" biological systems. Common techniques include directed evolution, metabolic engineering, or rational drug design.


Although I've just spent time developing a distinction between the two fields, many labs and many scientists frequently employ techniques of both in their research. For example, labs that are very skilled at synthesizing organic small molecules might also employ mutagenesis to tweak their enzyme target of interest (4). Or, a graduate student trained in biophysical methodology might elect to do a more chemically-oriented post-doc, applying fresh perspective to new problems.

Working at the intersection of biology and chemistry sometimes has interesting consequences, but I feel that one of the main barriers between these fields is the lack of cross-talk. Advances in one field may be overlooked, simply because the results are presented in an unfamiliar language. In my opinion, this is why interdisciplinary training is so valuable. Training in biochemistry or chemical biology allows scientists not only to "speak the language" of each field, but to apply the best techniques to the most interesting biological questions.
