Biochemistry:Work of a biochemist

Definition and Nature of the Work

Biochemists are scientists who study the chemistry of living things. Their work includes studying the complex chemical combinations and reactions involved in metabolism, reproduction, growth, and heredity.
Some biochemists do basic research that expands scientific knowledge about the chemistry of living things. Others do applied research—that is, they work to create new products or to solve practical problems. In the field of medicine, for example, biochemists doing basic research may study the ways hormones are formed. Biochemists doing applied research may use the basic findings of hormone formation to develop synthetic hormones that can be produced on a large scale.

Biochemists working in medicine are sometimes called molecular biologists. They study bacteria, viruses, and other organisms to better understand the chemical basis of life. They also determine the effects of chemicals on medical problems such as cancer, aging, or obesity.
Biochemists in nutrition analyze food products to measure their vitamins, proteins, carbohydrates, and minerals. They research the effects of freezing or cooking and compute the caloric value of foods.
About half of all biochemists work for colleges and universities, where they teach or do research. Many are employed by private firms such as breweries, drug companies, petroleum producers, and manufacturers. Others work for nonprofit research centers or government agencies. A few biochemists are self-employed consultants who advise the government or industry.
Although their jobs may differ widely, almost all biochemists do laboratory research at least some of the time. They plan research projects to test theories or to develop new products or processes. They are often assisted by laboratory technicians or research assistants. Biochemists perform a number of tasks, such as weighing chemicals, filtering liquids, distilling ingredients, and growing cultures of microorganisms. They use a variety of tools and instruments, including test tubes, beakers, flasks, electron microscopes, centrifuges, and spectrophotometers. Sometimes they make use of radioactive isotopes. Biochemists must use exact scientific methods in their work. They are often aided by computerized Biochemists conduct their research in laboratories and then use scientific methods and computer programs to analyze their data. (USDA-ARS.) data. Biochemists generally write up their findings for scientific journals and report them before groups of scientists.

Education and Training Requirements

High school students interested in biochemistry should take chemistry, biology, physics, mathematics, English, and foreign language. By participating in science clubs, science fairs, and summer programs sponsored by the National Science Foundation, secondary school students can get experience in science-related work. You usually need a doctoral degree to become a biochemist. You should major in biochemistry, biology, or chemistry as an undergraduate and continue with specialized training in biochemistry in graduate school. Individuals with bachelor's degrees are sometimes hired as research assistants or technicians. They often do routine testing and analysis, but their opportunities for advancement are limited. People who have earned master's degrees in biochemistry are qualified for more responsible jobs in applied research and for some teaching jobs. You usually need a doctoral degree (Ph.D.) to teach and do research at a university or to move into a management or administration job. It generally takes four years to earn a bachelor's degree and another one or two years to receive a master's degree. You need to spend an additional three or four years for a doctoral degree. To keep up with new developments in the field, you should continue to read and study throughout your career.
Some biochemists get a doctoral degree in biochemistry after they have completed medical school and received the degree of doctor of medicine (M.D.). Medical training is needed by scientists who want to do certain kinds of research involving human beings.

Working Conditions

Biochemists generally work in well-lighted and well-equipped laboratories. Sometimes they spend time in offices and classrooms as well. The basic workweek is usually forty hours long. Hours are sometimes flexible, and they often total more than forty hours a week. Sometimes biochemists must work in rotating shifts if a project needs to be monitored around the clock. Biochemists also need to spend time reading and studying to keep up with other scientists' findings that are related to their own work.
