The energy released upon the complete degradation of 1 g carbohydrate and 1g lipid in the body has to be compared. Concept introduction: Carbohydrates and fatty acids, both are major sources of fuels. However, fatty acids yield approximately 2.5 times as much energy per gram as carbohydrates (glucose). Fatty acids are comparatively much better than glucose as energy storing molecules. In the body, some organs prefer to use glucose as a source of energy while functioning while some prefer fatty acids. There are also certain organs which prefer both.

Question

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures. Compound C Possible conformations (circle one): Дет

For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically: 1:1 (one mole of EDTA per mole of metal ion) 2:1 (two moles of EDTA per mole of metal ion) 1:2 (one mole of EDTA per two moles of metal ion) None of the above
