Summary:

Although this app may have been designed primarily for scientists who work in the field of mass spectrometry-based proteomics, it turns out to be a handy reference for any life scientist. The app is divided into three sections: solutions, proteins, and chemicals. The “proteins” tab includes mass spectrometry-based tools, such as calculated peptide fragmentations and mass shifts. There is also a convenient chart of amino acid properties. So what are the more general resources? The “solutions” section includes a tool that calculates the molecular weight of a user-entered molecular formula. This molecular weight can, in turn, be inputted to the stock solution calculator. The third component of the app, “chemicals,” includes a tool to identify metabolites from a parent compound; there are also lists of detergent properties and information about each of the atomic elements.
