Explore these six main areas of chemistry to learn what chemistry professionals do in each area and what kinds of jobs are available.
The science of obtaining, processing, and communicating information about the composition and structure of matter. The study of the structure, composition, and chemical reactions of substances in living systems.
Clinical biochemistry — the study of the changes that disease causes in the chemical composition and biochemical processes of the body. Agricultural biochemistry — the study of the chemistry that occurs in plants, animals, and microorganisms. There is a huge overlap between Chemistry and Biology, Medicine, Physics, Geology, and many other disciplines. What are the branches of chemistry and their definition? Chemistry Introduction What Is Chemistry?
Ernest Z. Dec 26, Organic chemistry overlaps with many areas including Medicinal chemistry —the design, development, and synthesis of medicinal drugs. It overlaps with pharmacology the study of drug action. Polymer chemistry — the study of the chemistry of polymers. Physical organic chemistry — the study of the interrelationships between structure and reactivity in organic molecules. Stereochemistry — the study of the spatial arrangements of atoms in molecules and their effects on the chemical and physical properties of substances.
It covers all chemical compounds except organic compounds. Branches of inorganic chemistry include: Bioinorganic chemistry — the study of the interaction of metal ions with living tissue, mainly through their direct effect on enzyme activity.
Examples of areas using analytical chemistry include: Forensic chemistry — the application of chemical principles, techniques, and methods to the investigation of crime. Sub-branches of physical chemistry include: Photochemistry — the study of the chemical changes caused by light.
Genetics — the study of genes, heredity, and variation in living organisms. Thus, although there are FIVE main branches of chemistry, there are many sub-branches. Related questions How do chemistry and biology relate? How does chemistry relate to cooking? Traditional organic chemists are concerned with synthesizing new molecules and with developing new reactions that might make these syntheses more efficient.
The kinds of molecules organic chemists synthesize include useful things like drugs, flavorings, preservatives, fragrances, plastics polymers , and agricultural chemicals fertilizers and pesticides , and sometimes include unusual molecules found in nature or ones that might simply provide a challenge to make.
Also, understanding something about organic chemistry is essential for learning about biochemistry and molecular biology because bio-molecules such as proteins, sugars, fats, and nucleic acids DNA and RNA are all organic molecules, albeit very large ones. Students who concentrate in organic chemistry typically go on to work in pharmaceutical, food or polymer companies, do research or teach in organic chemistry, pursue medical careers, or may pursue other related job opportunities.
Analytical Analytical chemistry is the science of identification and quantification of materials in a mixture. Analytical chemists may invent procedures for analysis, or they may use or modify existing ones. They also supervise, perform, and interpret the analysis. Physical Physical chemistry is the study of the fundamental physical principles that govern the way that atoms, molecules, and other chemical systems behave.
Physical chemists study a wide array of topics such as the rates of reactions kinetics , the way that light and matter interact spectroscopy , how electrons are arranged in atoms and molecules quantum mechanics , and the stabilities and reactivities of different compounds and processes thermodynamics. In all of these cases, physical chemists try to understand what is happening on an atomic level, and why. Students who concentrate in physical chemistry may go onto pursue careers in industry, research or teaching.
A lot of the current physical chemistry research in industry and academia combines the techniques and ideas from several fields. For example, some chemists apply physical chemistry techniques to investigations of the mechanisms of organic reactions what collisions and bond rearrangements occur, how fast are they, how many steps are there, etc.
Others apply physical techniques to the study of biological systems why do proteins fold into the shapes that they have, how is structure related to function, what makes a nerve work, etc.
Still others may use physical techniques to characterize polymers or study environmental systems. Inorganic Inorganic chemistry is commonly thought of as those areas within chemistry that do not deal with carbon. However, carbon is very important in many inorganic compounds, and there is a whole area of study known as organometallic chemistry that is truly a hybrid of the traditional disciplines of organic and inorganic chemistry.
