(a) Interpretation: Whether MES, MOPS or HEPS is effective at pH 7.0 should be determined. Concept introduction: The effectiveness of a buffer can be determined by the fact that the pH values and the p K a lies close to each other. If this value is not close the buffer will not be effective.

Question

What biochemical function do these Omega-3 fats play? Much cheaper alternative sources of omega-3 fats include fats from some seeds and nuts (most often from flax seed in consumer products), but the allure of fish oil sources maintains these products' popularity despite much higher prices. Is there a difference in the omega-3 fats derived from plant and animal sources? If so, explain the difference and why one is "better" than the other.
