(a)
Interpretation: The validation of the fact that bioorganic substances are much more abundant than bioinorganic substances concerning human body composition, in terms of mass percent has to be stated.
Concept introduction: The chemical substance found in the living organism is called biochemical substance. The biochemical substance is further subdivided into bioinorganic substance and bioorganic substance. Bioinorganic substances do not contain carbon, for example water and inorganic salts. On the other hand bioorganic substances contain carbon, for example lipids and carbohydrates.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
