Role of Trace Elements
Element having average concentration of less than 100 ppm is referred to as trace elements. For living system, trace element is needed in minute quantities for the proper growth, development and physiology of organism. In biochemistry, a trace element is also referred to as micronutrients. A large number of elements are required in trace amount. Generally they play a role in catalyzing the enzyme. Some of the major trace elements needed by animals are as follows :-
a. Cobalt is required for biosynthesis of vitamin B12 family of coenzymes
b. Copper is required component of many redox enzymes, including cytochrome c oxidase of electron transport system in mitochondria
c. Fluorine for tooth enamel which contains fluoroapatite (see Water fluoridation controversy)
d. Iodine is required for the biosynthesis of thyroxin, is required in larger quantities than the other trace minerals in this list and is sometimes classified with the bulk minerals
e. Iron is required for many proteins and enzymes, notably hemoglobin
f. Manganese (processing of oxygen)
g. Molybdenum is required for xanthine oxidase related oxidases
h. Nickel present in urease
i. Selenium is required for peroxidases which act as antioxidant proteins
j. Zinc is pervasive and required for several enzymes such as carboxypeptidases, carbonic anhydrase
Important Trace elements required in Plants are as follows :

PowerPoint Presentation on the Element Boron
I am looking for someone who is knowledgeable with PowerPoint.
I need help getting started with this project and knowing how to go about this.
My classmates told me finding a scientific article is the hard part to this project, so I want someone to help me with that also.
As a class, we will begin the construction of an interactive Periodic Table for the Health Sciences. Students will be assigned one element each for research. A PowerPoint presentation will be constructed fro each element.
The slides should be saved as ppt files. All sources (websites, journal articles, books) must be cited in a such a way that they could be relocated (cite websites as www.website.com; articles with author name, date, title, journal name and volume, and page numbers; books with author name, date, title of book, and publisher; use a small font). You must have at least two graphics in your presentation with explanatory captions.
Content/Format for slides: each presentation will consist of four slides.
1) General Information: name of he element and its symbol; basic information
2) "Element of Health" - include the roles of the element in normal physiology
3) 'Element of Disease" - include diseases/conditions related to the element
4) Summary of a scientific article (the article must be related to the health aspects of your assigned element)
I will judge based only on the following criteria: 1) format followed with two art/graphic pieces with captions, 2) slides regarding health and disease on topic and minimum of 50 words, 3) summary of scientific article included, 4) overall impressions (neatness, grammar, spelling), and 5) sources cited.View Full Posting Details
