What is the Chemical Structure of Vitamin K?

submitted by: AntonyWilliams
You would think that finding the correct structure of Vitamin K1 online in public domain resources would be an easy exercise. But not so fast. Using the assertion that the chemical structure is correct in the Merck Index, and then wandering through CAS’s Common Chemistry to validate this assumption, this short movie takes us through Wikipedia, Wolfram Alpha, KEGG, DrugBank, PubChem and other online resources to show how complex and impure the public domain databases are in terms of...

How Community Crowdsourcing and Social Networking is Helping to Build a Quality Online Resource for Chemists

submitted by: AntonyWilliams
With an intention to provide a free internet resource of chemistry related data for the community, ChemSpider provides an online database of chemical compounds, reaction syntheses and related data. Members of the community can contribute to the database via the deposition of chemical structures, synthesis procedures and analytical data. Data are also aggregated from many other depositors, at present over 400 data sources. The aggregation of data associated with over 25 million chemical...

Citizen Scientists and Their Contributions to Internet Based Chemistry

submitted by: AntonyWilliams
This presentation was a presentation to a group of chemistry students at Drexel University. The premise of this presentation was an overview of the ChemSpider search engine and database but during the process of teaching about ChemSpider an overview of various aspects of internet based chemistry were given. This included: the quality of chemistry-related data online, an overview of InChIs as a basis for searching the internet by chemical structure and semantic markup of chemistry articles.
