This paper will try to describe what iron is in chemotherapy or in biology. This description will be biological in nature. The description will include the elements of iron and its basic properties and also the roles of iron in the body. …
The study would focus on iron as both a chemical element and a metal. It is the most common element that is found both in the inner and outer core of the earth. Iron exists in different states of oxidation and it occurs in environments with low oxygen rates. Iron plays an important role in biology in that it forms complex structures with oxygen in hemoglobin and myoglobin. Hemoglobin is a protein which contains iron and is used in transporting oxygen. It is found in the red blood cells in all vertebrates apart from the fish family. It is used to carry oxygen from the lungs to the rest of the body to help in providing energy to nutrients that are burnt up so that the organism can function effectively. In mammals, hemoglobin makes up almost all of the red blood cells. It also carries other gasses apart from oxygen such as carbon dioxide and nitric oxide, and it is also found outside red blood cells. Myoglobin is a protein which has iron and is oxygen binding. It is found in the tissue of vertebrates. Myoglobin is not found in the blood unless it is released when a muscle is injured. It has a single chain protein with eight alpha helices with a hydrophobic core. Iron is found in all living things including human beings. The color of the blood is usually characterized with the amount of hemoglobin in the blood. The hemoglobin is a protein which contains iron. Iron is usually bound to cofactors such as the hemes. Enzymes and proteins which contain iron usually take part in many biological oxidations and transportation processes. Iron is very pervasive and it is found in various diets or foods such as red meat, lentils, beans and fish. There is a high amount of iron contained in these foods. It can, however, be found in low amounts in molasses and teff. Iron in meat is usually more easily absorbed than iron in vegetables. Iron provided by foods or dietary supplements is usually found as iron fumarate. This is an iron salt of fumaric acid which appears as a reddish powder used as a supplement in the intake of iron (Williams 2011, p. 109). Iron sulphate is usually cheaper and easily absorbed as compared to fumaric iron. Elemental iron which is also known as reduced iron is usually absorbed ...

Iron is a part of several macromolecules in the human body involved with production of energy by the formation of adenosine triphosphate molecules, ribonucleoside reductase activity in DNA synthesis and xenobiotic metabolism (He et al, 2007; MacKenzie et al, 2007).The macromolecules consist of hemoglobin, cytochromes, oxygenases, flavoproteins, and redoxins. This makes iron a significant part of the vital biologic processes in human beings. Iron has a dichromatic nature; it is able to participate favourably in production of energy by electron transfer and can be simultaneously toxic by electron transfer in oxidation-reduction reactions (MacKenzie et al, 2007).
The paper describes the roles of iron in the body, what it does and how it does it, describes the various elements that help iron in its functioning, looks into detail the absorption process of iron in the body and how iron is absorbed and which forms of iron are absorbed in the body. It includes a detailed description of the entire absorption process.
Beginning in the early 1970s forensic laboratories have quadrupled in response to the proliferation of substance abuse, an increasing demand for independent evidence and advances in science and technology (Peterson & Sommers, 2010).
This study is comprised of two separate sections. 77 participants were asked to comment on a news article and the way that this could affect the eating disorders and body image of an individual. 18 of these then completed a focus group discussing the role of the media in the development of eating disorders and negative body image.
These colors range from bright yellow, grey, deep purple or sometimes rusty red. This iron is in the form of hematite, limonite, magnetite and siderite. Natural ores are usually ores carrying extremely high quantities of hematite or sometimes magnetite. The main reason for this is its usability in blast furnaces making iron.
The paper evaluates the role of nutritional diets for such patients who suffer from chronic wounds. The research takes into account the factors that either impede or foster wound healing during the various phases of wound management. The paper identifies the potential nutritional needs of the older population in U.K who are found to be extremely vulnerable towards chronic wounds.
Therefore, the vendors are looking for new ways to develop effectives advertising and branding strategies that may positively influence consumer purchasing decisions. A combination of advertising and branding is required because a brand name explicitly convey the product features and results in a higher recall of advertised feature (Keller, Heckler & Houston, 1998).
With this concern, the paper focussed on the laptop market of Leeds in the UK. Research Methodology: The research process was based on a qualitative approach considering the fact that most of the concepts related with brand loyalty and advertising are observed to be qualitative in nature.
This paper examines CSR activities focusing on The Body Shop. The Body Shop is the second largest cosmetic franchise in the world and founded by the late Dame Anita Roddick. The Body Shop has emphasized its support for a wide range of issues around the globe. The company is noted for a range of product environmental innovation.
Thus internal environment of the body is maintained by a close surveillance system and timely response to any change which may affect homeostasis. This adjustment of physiological systems within the body is called homeostatic regulation (Wikiepedia 2007).
