Extract of sample "Zinc"

Response Though the importance of Zn for cellular functions cannot be overemphasized, high concentration of Zn makes it a potential pollutant in the river. Zn in high concentration is capable of binding to unwanted enzymes and proteins and replacing other metals, thus causing the enzymes and proteins to be deactivated. To provide the plants with appropriate conditions to survive, it is imperative that a very controlled homeostatic network is created that comprises trafficking, export, import, and sequestration (Olsen and Palgram, 2014).
Factors that contribute to the increase in the amount of Zn in the rivers include but are not limited to such human activities as industrial and urban sewages, runoffs, and atmospheric sediments. More than anywhere else, presence of such elements as Zn in excess in the river water is more dangerous since it reaches the livestock and humans directly or indirectly.
A great variation in the behavior of Zn is also evident from the fact that while it is brittle at low temperatures, Zn becomes quite ductile and malleable at temperatures reaching anywhere between 110 and 115C. Just as it changes in its physical properties with temperature, Zn changes in terms of its effects on the environment when it gets in excess.
This is a wonderful and very informative essay about the effects of Zn in the environment which is often considered as an element that cannot affect the environment in harmful ways. This is an important issue and needs to be explored and studied in detail in order for all the confusions and misconceptions surrounding it to be eradicated.

Zinc Finger Nucleases

...?DEPARTMENT OF BIOLOGICAL SCIENCES COVERSHEET FOR ESSAY (PG) DEADLINE midday (12:00pm) Friday of week 22 OF ESSAY: Site-directed mutagenesis of gene sequences in cells of plants, insects and animals can be achieved in situ used engineered zinc finger nucleases (ZFNs) linked to the specific restriction endonuclease FokI. When mRNA or genes coding for modified ZFNs are expressed in cells they introduce site-specific breaks in target DNA, which when repaired by the cellular DNA repair machinery, result in substitutions or deletions at the cleavage site, thus introducing a site-specific mutation. 1) Cite four research papers that use this method (20%) and describe, with the aid of diagrams if necessary. 2) How ZFNs can be...

Zinc and Vitamin D

...?Discuss the nutrients Zinc and Vitamin D and the food sources. Think about why you need the nutrient and if you are likely to be getting enough. 300words is still the minimum. Certain elements are necessary for the survival of human beings. Vitamin D and Zinc are two essential elements which are required by the human beings. Both of them have their own important functions which are necessary for the survival of the body. Zinc is a metallic element which is an essential product required by our body. It is present in some foods naturally alongwith certain drug supplements which contain the essential element. It is quite important in the metabolic functions of the body as it helps in improving the activity of the enzymes in the body... . It is...

...?INTRODUCTION TO ZINC: Zinc has its origin form the German word “Zin” which means Tin. Zinc is found in the group IIb in the periodic table. Zinc is a transition metal having a lustrous blue white appearance. At the ordinary room temperature, the appearance of zinc is crystalline and brittle. But it varies with different temperatures, as the appearance becomes ductile when heated at ranges 110-150 °C. Zinc is a reactive metal that was first discovered in 1746, and the person who discovered zinc was Andreas Marggraf. The symbol of zinc is denoted with “Zn”. Being in the group of transition metals, it is...

Zinc Requirements for Teenagers and Children

...Zinc Requirements for Teenagers and Children Zinc is a vital trace mineral that contributes in a big way to the general health of developing children as well as teenagers. In Australia, a few researches have been conducted on zinc intake among Australian teenagers and children in recent years. Zinc contributes towards the development of the neurological, reproductive, and immune systems in children. In the 1960s, the incidence of a severe zinc deficit resulted in hypogonadism, growth retardation, and delayed sexual maturation (Sertori 2008). Zinc deficiency has also been known to result in infections such as diarrhoea, and pneumonia, the...

Zinc finger proteins

... Zinc Finger Proteins Zinc finger proteins (ZFP) can be conceptualized as protein subunits that are compact in nature and have chains of structured peptides that fold and encompass zinc ions. They have many functions within eukaryotic cells such as mediating in binding interactions among proteins and provision of structural scaffolds that are stable (Isalan 435). Their first recognition was as motifs that bind zinc in a repeated manner having ligands of conserved histidine and cysteine within them. Many families of ZFP exist that are differentiated through their structure and folding characteristics but the most abundant and well studied is the classical “Cys2–His2” (Laity, Lee, and Wright 39) The nature of ZFP... is such that they...

Contacts to ZnO (zinc oxide)

...vacancies and zinc interstitials that lead to high donor concentration on the surface. Additionally, the range of barrier heights on ZnO for a given metal is wide and varies greatly. For instance, Au contact on ZnO can yield barrier heights ranging from 0 to 1.2 eV. Similarly, the contacts formed by metals such as Pt and Ta result in barrier heights that vary on large scale. The practical situation where the n-type barrier heights for contact with high work function metal are lower than expected range, poses another problem. Thus using this latter piece of information, it can be inferred that the Schottkey barrier heights are related to work function of different materials [8]. One published work suggests that the high...

EXP #4 Synthesis Zinc Iodide

...Exp #4 Synthesis Table of Contents I. 3 II. Introduction 3 III. Experimental 3 A. Materials 3 B. Methods 3 IV. Results 4 V. Discussion 5 References 7 I. Abstract In the laboratory, zinc iodide was synthesized from the reaction of zinc and iodine reactants. The final product was weighed and measured and the reaction yields were measured. The physical characteristics of the solution of zinc and iodine were observed and noted, especially with regard to the changing colors of the solution as the reaction progressed. These observations are correlated with the changes in the composition of the solution as iodine was drawn out of it, and with regard to the iodine as the limiting reagent in the reaction. The law of conservation of mass... is...

Introduction of Synthesis of Zinc Iodide

...Your Full Your Experiment 4: Synthesis of Zinc Iodide Introduction The reaction of two or more reagents, elementalor as compounds, given the right atmospheric and physical conditions is commonly known as chemical synthesis, and is governed by the Law of Conservation of Mass. This law was proven by Antoine Lavoisier (1743 – 1794), and stated that matter can go through any physical or chemical reaction, but the total mass of the reactants and the products will remain equal (Rogers et al., The experiment aims to illustrate the Law of Conservation of Mass by reacting zinc metal and iodine to synthesize zinc iodide. The chemical equation (Eqn 1) below presents the synthesis of...

Zinc and alcohol metabolism

...Zinc and Alcohol Metabolism Zinc and Alcohol Metabolism Zinc is an important trace element in animals, plants and humans. It is essential for most biological functions as well as playing a role in up to 300 enzymes in the human body. An adult body contains 2-3 grams of zinc and are found in all body parts: cells, fluids, bones, tissues and organs. Most of the body’s zinc reserves are found in bones and muscles, while higher concentrations are found in semen and the prostate gland. Zinc is majorly present in foods rich in proteins, which is absorbed in the ileum and duodenum by the intestinal epithelium (Bolkent et al, 2006). The ileum...

Zinc and immunity

...Zinc and immunity By Introduction Zinc plays a vital task in the immune system. People that are zinc-deficient experience amplified vulnerability to a range of pathogens. The immunologic means by which zinc alters increased vulnerability to infection have been investigated for many decades. It is apparent that zinc controls many facets of the immune system, starting with the skin barrier to gene regulation inside lymphocytes. Zinc is central for usual development as well as the function of cells arbitrating imprecise immunity like neutrophils along with natural killer cells.1 Zinc insufficiency also manipulates...
