LCMS Assembly of Cholesterol

  1. Feb 22, 2012 #1
    1. The problem statement, all variables and given/known data
    Our assignment was to determine the structure, or sub-structure of our mass observed in the LCMS result. The number we got was 369.3. I am not really sure what to do with this at all. She gave us the structure of cholesterol, but I'm not sure where to add things on...

    387.3. I think I actually understand it now. because the LCMS will show the mass +1 and then the bond with water was broken, which caused the weight to be 18 less than what we expected.?
