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...

    Add things on? Molecular mass of cholesterol is ... what?

    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.?
