Time to hemolysis RESULTS (cont.) Table 5: Hemolysis results for organic compounds Compound Molecular formula Expanded Molecular Hemolysis formula (y) H2NCONH2 1. Urea C.H.OH 2. Ethyl alcohol 3. Propyl alcohol CH.CH.CH.OH 4. Ethylene glycol CH,OHCH,OH 5. Propylene glycol CH,CHOHCH OH 6. Glycerol CH,OHCHOHCH OH 7. Glucose C6H1206 DATA ANALYSIS AND REVIEW QUESTIONS (for Table 4- inorganic salts): 1. What general conclusions can you draw from Table 4? 2. What features of ammonia probably contributed to its ability to cross the rbc membranes? 3. Urea and NaCl have very similar molecular weights (60g/mole and 58.5g/mole respectively), s why is there such a huge difference in their membrane permeability?? 4. Test tube 4 actually contains NH4OH. How would the NH4+ react with OH-in a basic solution? What products would form? Which product is the key for this experiment? Draw the equation!
