Silicon is a metalloid element commonly found in Earth's crust. It helps form many different compounds, which have a variety of different properties and applications. One type of silicon-containing minerals is asbestos. Asbestos is resistant to heat and electricity, leading to its widespread use in manufacturing and the construction industry. Asbestos insulates buildings and makes them fire resistant. However, despite its usefulness, exposure to asbestos fibers or dust carries serious health risks that can cause respiratory disease or cancer. Another silicon-containing compound is orthosilicic acid. Unlike asbestos, orthosilicic acid seems to benefit human health. This compound readily dissolves in water and is biologically stable enough to be used in the human body. Scientists have found evidence that orthosilicic acid plays an active role in the maintenance of strong bones. The information above shows that silicon has both beneficial and detrimental effects on the human body.…
Zinc in its 2+ oxidation state is an essential metal ion for life.Zn2+ is found bound to many proteins that are involved inbiological processes, but unfortunately Zn2+ is hard to detectby common chemical methods. Therefore, scientists who areinterested in studying Zn2+-containing proteins frequentlysubstitute Cd2+ for Zn2+, since Cd2+ is easier to detect. (a) Onthe basis of the properties of the elements and ions discussedin this chapter and their positions in the periodic table, describethe pros and cons of using Cd2+ as a Zn2+ substitute.(b) Proteins that speed up (catalyze) chemical reactions arecalled enzymes. Many enzymes are required for proper metabolicreactions in the body. One problem with using Cd2+to replace Zn2+ in enzymes is that Cd2+ substitution can decreaseor even eliminate enzymatic activity. Can you suggest a different metal ion that might replace Zn2+ in enzymes insteadof Cd2+? Justify your answer.
