Denaturation - Study guides, Class notes & Summaries

Denaturation - Answer When natural proteins are subjected to physical/chemical treatment and their structures change They become "un-native or "unnatural" What does heating proteins do to them? - Answer Imparts energy to the molecules This added energy breaks the relatively weak forces that hold the protein together (in tertiary and secondary structures) As the heat continues, the protein molecule unfold more and more The hydrophilic regions are now exposed to the outside of the molecu...

After experiencing extreme fatigue and polyuria, a patient's basic metabolic panel is analyzed in the laboratory. The result of the glucose is too high for the instrument to read. The laboratorian performs a dilution using 0.25 mL of patient sample to 750 microliters of diluent. The result now reads 325 mg/dL. How should the technologist report this patient's glucose result? A. 325 mg/dL B. 1300 mg/dL C. 975 mg/dL D. 1625 mg/dL - B; The correct answer for this question is 1300 mg/dL. The ...
