With an accompanying brief narrative, write a short lab report (brieflydescribing what you did) and in a results section, show your standard curve andtabulate the concentration of the unknown protein samples provided using thethe Bradford Assay and UV absorbance)

What two procedures should you routinely carry out to verify the purity of your working stock?

13) True or false: fragmentation spectra obtained from a mass spectrometer can help identify molecules with similar structures.

Sucrose + H2O(negative control): Colorless to brown solution: Blue solution Conclusion for Iodine test A. amylose present B. amylose not present Conclusion for Benedict's test A. reducing sugars not present  B. reducing sugars present  Sucrose + HCl(potential hydrolysis): unchanged compared to sucrose+water:  Conclusion for Iodine test A. more amylose present B.  LESS amylose present C. NO change  Conclusion for Benedict's test a. more reducing sugar present  b. less reducing sugar present   c. no change  Did hydrolysis of sucrose occur in the presence of acid? A. Yes  B. no

To analyze a sample by mass spectrometry, the sample must consist of gas phase ions. a) Explain why it is difficult to make gas phase ions of proteins.   b) Generally explain how electrospray ionization turns proteins in solution into gas phase ions.
