For centuries, many scientists and researchers have pondered on the idea of combining two or more substances together to create something new. These explorations have led to the idea of what kind of reactions would occur when diverse elements are combined. This is a concept known as chemistry, a part of science that corresponds with how matter is created from different properties and the process it goes through to create a new substance. Chemistry is a scientific concept that is used in everyday life and is a crucial part in the development of new technology and substances that allow today’s quality of life. The use of chemistry branches off into many different routes, including medical related fields, agriculture, and even in weapons of …show more content…
This science is directly associated with chemistry through different concepts and applications. In order to be successful this division of science, a biochemist needs to have a strong understanding of atomic structure in various molecules and elements. They need to be able to understand the structure of the diverse molecules that they are working with and should be able to predict the outcome of certain chemical reactions. Furthermore, biochemists should be just as aware of certain molecules and substances that would not react well together. Ultimately, one of the biggest factors in biochemistry is being able to balance the molecules of the substance that is being created. However, biochemists not only need to be sure that the substance they are creating is balanced, but the substance created balances when combined with living organisms. If the substance created reacts poorly with the chemicals within a living organism, the outcome could very dangerous. Since there are important concepts a biochemist needs to understand, there are some specific chemistry concepts that they must apply. A basic concept they must know, as previously stated, is stoichiometry. Stoichiometry is vital to biochemists because they need to know how to balance certain substances to achieve the reaction they want. Since they are also working on the molecular …show more content…
Biochemists will use advanced electron microscopes and lasers along side with computer modeling software to conduct molecular research. Along with conducting research projects, biochemists will typically be involved with many laboratory projects to provide information on various findings to other scientists and interested outside parties. Since this is an occupation that can be varied by different levels of education, biochemists with a higher degree will typically be better compensated. The average starting starting salary of a biochemist with a bachelor’s degree is around $50,000; starting salaries for both biochemists with a master’s or a doctorate also follow as $60,000 and $90,000 a year. All of these starting also vary depending on the location the biochemist is employed at. With starting salaries lower than the national average, biochemistry is an occupation that can be found in Idaho. The major job sites in Idaho range from areas around Boise, through Pocatello, and up Idaho Twin
Cu (aq) + 2NO3 (aq) + 2Na+ (aq) + 2OH- (aq) → Cu(OH)2 (s) + 2Na+ (aq) + 2NO3(aq)
The major sites for the production of ammonia are the intestines, liver, and kidneys. It is biosynthesized through normal amino acid metabolism. The kidneys generate ammonia from glutamine by the actions of renal glutaminase and glutamate dehydrogenase. Ammonia is formed from urea by the action of bacterial urease in the lumen of the intestine, which is absorbed from the intestine by the portal vein. Amines obtained from diet and monoamines that serve as neurotransmitters or hormones can create ammonia by action of amine oxidase. In purine and pyrimidine catabolism, amino groups attached to the rings are released as ammonia.
A huge fascination of arsenic started in the 19th century when people got word of a province in southeastern Austria where people ate arsenic. Women would eat arsenic to help gain weight and fix their complexion to look more beautiful and men would eat arsenic because they believed it helped them breath easier when they were climbing high up in the mountains. One doctor by the name of Dr. Robert Craig MacLagan, was particularly interested in this and visited the town to see for himself what was really occurring. He observed the people and tested their urine to prove that they have been indeed ingesting arsenic. He wrote about the things he witnessed in the Edinburgh Medical Journal. The men in the town would eat 6 grains/dose at least twice a week, sometimes eating it on their bread or just drinking it with their water. As a result many Victorians began self-medicating themselves with arsenic.
.... Without these systems humans would be extinct, because these systems provide humans the nutrients, energy, oxygen, and many other substances that humans cannot live without. All these systems and functions work together as a whole. Biochemistry helps develop medicine and medicine is used every day in life. Without medicine many diseases and flus would not be cured. But not everyone catches or has the same types of diseases or flus, therefore biochemists developed different medication for different bodies and flus. But it is in the hands of the doctors, pharmacists, or the physician’s to prescribe the right medication for the patient, and this is taught in biochemistry. Therefore a student who wants join to the medical field should study human anatomy so the he/she is aware of the human structure. And also study biochemistry to have strong knowledge in medicine.
I have always been inspired by the workings of chemistry and mathematics. My studies of these subjects have developed my understanding and have made me pursue my interest in these two topics. I want to take up chemistry as it involves a large amount of mathematics which I value and understand to be challenging, yet very enjoyable, as there is always an alternative route to obtain the answer. Additionally, I am drawn to the course because it is a mixture of all these exacting subjects, forming a degree that is very demanding and stimulating. Chemists are constantly thinking of new ways to produce viable drugs containing different isomers to improve the pharmaceutical sector using mathematical equations. Chemistry is about innovation, applying information to new areas and how to do things better than they were before, the degree appeals to and fascinates me.
Biomedical sciences are the set of applied branch of life and natural sciences, which is used for diagnosis, prevention and treatment of human diseases. There are various streams of biomedical science including human biology, pathology, biochemistry, molecular & cell biology, genetics, pharmacology, immunology, applied or clinical chemistry, microbiology, epidemiology, and biomedical engineering. Modern advancements in medicine depends a lot on the work of biomedical scientists. However, the subject is NOT a substitute for Medicine.
Ammonia (NH3) is a very imperative substance or product that is used day to day in everyone’s lives. Ammonia (NH3) is used to produce fertilizers, household cleaning products and is the starting material for many explosives and many pharmaceutical products. Ammonia (NH3) is also used to create nitric acid (HNO3), also a very crucial substance used in our daily lives. The Haber process is the industrial process for the manufacture of ammonia (NH3) from hydrogen (H2) and nitrogen (N2), if not for the Haber Process there would be massive shortage and impact of ammonia (NH3) in our lives, hence higher rate of famine and more time to clean household products and creation of pharmaceutical products, by which you can tell that the Haber process and
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
To control the rates of chemical reactions is imperative to the continued existence of our species. Controlled chemical reactions allow us to move forward in society, constantly. We find new ways to provide light and heat our homes, cook our food, and pursue in crafts that benefit our society. There are, however, just as there are advantages, disadvantages to the efficiency of controlling the rate of reactions, which in some cases can be fatal to our scientific development and progression. The growth of humankind necessitates that we must be able to control the rate of chemical reactions.
I have always been intrigued by the field of science and that is the reason I pursued the field of Biochemistry for my undergraduate studies. How The Human body works and the different determinants that can affect one's health or a community as a whole have always been captivating to me. I wanted to emerge in a profession that is beneficial for me, my community, and the world I live in. I came to realize through various science courses and health care experiences that a career in health care was the best path for me to outreach my community and the world.
Phosphorus does not access the atmosphere, remaining chiefly on land and in rock and soil
Biochemists are scientists who study the chemistry relating to, biological organisms. It forms a bridge between biology and chemistry by studying how complex chemical reactions and chemical structures give rise to life and life's processes. Their work includes studying the complex chemical combinations and reactions involved in metabolism, reproduction, growth, and heredity. Biochemistry is sometimes viewed as a hybrid branch of organic chemistry which specializes in the chemical processes and chemical transformations that take place inside of living organisms, yet the reality of the situation is that the investigation of natural chemistry ought to for the most part be viewed as none, of these completely “biology” nor completely "chemistry" in nature. Organic chemistry fuses everything in size between an atom and a cell and all the connections between them. The point of organic chemists is to portray in sub-atomic terms the structures, instruments and synthetic courses of action imparted by all creatures, giving sorting out standards that underlie life in all its diverse forms. All life forms alive today are generally believed to have descended from a single proto-biotic precursor, which could clarify why all known living things characteristically have comparative biochemistries (InnerBody. N.p., n.d.).
How did the world of chemical engineering start, what's the history of chemical engineering? Chemical engineering started with a man named George Davis who is credited with the concept of unit operations. Unit operations is analyzing the process of plants, such as water, petroleum, and petrochemical. They studied and made a process to move around and mix chemicals. Unit operations is the same concept of what we now know as chemical engineering. Davis was given the credit, but in 1977 a professor of chemical engineering reported that in 1880, Davis overheard a chemical manufacturer say something about chemical engineering. Although this was never proven, its still considered Davis’s idea. Chemical engineering is also the reason that the United
Biochemists are scientists who study the chemistry that is relate to the biological organisms. According to State university website “Their work includes studying the complex chemical combinations and reactions involved in metabolism, reproduction, growth, and heredity.” Biochemists have a verity of career positions or work environment where they can find themselves in. “Some biochemists study the body’s immune response to germs and allergens or the effectiveness of drugs in treating a wide array of afflictions. Other biochemists work in the commercial food or agricultural field looking for ways to improve products and crops” (Guide to Biochemistry Careers, 2013). Biochemists function in the medical field to help in the diagnosis of various manageable diseases by analyzing body fluids, urine and blood. These biochemists work in a pathological team or as a biochemical scientist in various hospitals and chemical pathology laboratory (Clinical biochemistry, n.d.). Biochemists analyze changes that occur in the biochemical structure of the human body to diagnose the disease and therapy, used to treat the biochemical change. Changes that occur in the human body, as a result of diseases, can be detected with the help of various techniques that find alteration in the blood, level of enzymes and its activities. Biochemists help in analyzing therapies and other clinical methods that can be used by doctors to treat such diseases (Clinical Biochemistry/ Clinical Biochemist, n.d.).
The growing relevance of Chemical Engineering in today’s world, from energy & oil industries to pharmaceuticals & biotechnology, and a keen desire for applying this knowledge in interrelated spheres motivates me to pursue a Master’s degree in this field. My interest in science goes back to the time when I was in school. We had a young and enthusiastic teacher who took us on field trips and visits to science fairs and museums. This nascent interest has only burgeoned through my years in school and high school, as I have learnt more about the subject. In the long run, I see myself as a part of a leading research group, either as a faculty member or in the R&D department of an organisation contributing my bit to the field of Chemical Engineering. As a research scientist, I hope to make a difference in this field and learn more through the innovative challenges.
