The Importance of Zinc in Our Bodies

- ... Zinc is best known for its role in protecting our skin in sunscreen. However, this is false. The in sunscreen is not actually zinc. The substance found in sunscreen is actually zinc oxide. One might say that the two are the same and they would be absolutely wrong. Zinc oxide is a synthetically made substance while zinc is naturally occurring in nature. Zinc has been used since ever since metal weapons were first created. Zinc was majorly used at the dawn of the Romans to make weapons and household items out of brass....   [tags: periodic table elements]

Zinc and The Common Cold

- The common cold is the leading cause of illness in the United States alone equaling to about 1 billion a year. In the continuing quest to find a cure for the common cold it was discovered in 1984 that zinc could possibly help shorten the duration of colds and reduce symptom severity (4). However some findings proved to be inconclusive when they tried to repeat the results. This paper will explore more recent studies on the effect of zinc on the common cold, and examine what further research should be explored....   [tags: treatment, symtoms, duration]

Selenium and Zinc within Human Thyroid Tissues

- Selenium is a nonmetal, essential trace mineral that exist in both the inorganic (selenide, selenite, selenate) and the organic (selenomethionine, seleneocystine) forms (5). Its main form: selenomethionine is found in plant sources and selenocystine in animal sources. This important micronutrient is found in high concentrations within the thyroid and perhaps in smaller concentrations in the kidney, liver and other tissues.() In humans selenium is carried out primarily by selenocystine which comprise protein enzymes (selenoproteins) which are found to have primary roles in thyroid hormone metabolism, antioxidant defense and in the immune function....   [tags: Graves’ disease, abnormalities]

Why Ratio Are An Integral Part Of Each One Of Different Activities And Ratios Tie These Activities Together

- Ratios are an integral part of each one of these activities and and ratios tie these activities together. In Dalton’s Playhouse the students were introduced to the use of ratios in chemical formulas by determining proportions of elements in a decomposition reaction. This led into the reaction of mossy zinc with hydrochloric acid by using the same knowledge base but in a new context, a single replacement reaction instead of a decomposition. In this activity the students had to use their own data to come up with their ratio for the product, zinc chloride....   [tags: Chemical reaction, Chemistry, Ratio]

Chemistry Experiment on the Reaction of Different Metals When Exposed to Acid

- Before the experiment, I wrote down a prediction. My hypothesis towards the experiment was that magnesium would have a bigger reaction with the acids. The reactivity of an element depends on its ability to gain or loose electrons which are used for bonding. The more reactive an element, the more easily it will combine with others. From this information, I know that magnesium has a stronger ability to gain or loose electrons which makes the metal more reactive. I gathered together four different metals and acid compounds which all reacted with one of the elements in the past, for example, Iron Sulphate (FeSO4) contain iron....   [tags: chemistry lab]

In Table 1, lead was utilized as the reduction half of each redox reaction in the galvanic cell, while the other metals acted as the oxidation half. Given that the concentration for each metal remained constant, this table is the basis for Table 2, which depicts the relative position of the reduction reactions when compared to the lead half-reaction. The most positive values reside at the top, indicating they have a stronger oxidizing agent, versus reducing, while the more negative values are more likely to reduce....   [tags: Electrochemistry, Galvanic cell, Redox]
