Genetics - the study of genes, heredity, and variation in living organisms. Molecular biology - the study of the interactions between the various systems of a cell, such as the different types of DNA, RNA, and protein biosynthesis. It spans molecular biology, genetics, biochemical pharmacology, clinical biochemistry, and agricultural biochemistry. It tries to explain them in chemical terms.īiochemical research includes cancer and stem cell biology, infectious disease, and cell membrane and structural biology. Spectroscopy - the use of the absorption, emission, or scattering of electromagnetic radiation by matter to study the matter or the chemical processes it undergoes.īiochemistry is the study of chemical reactions that take place in living things. It incorporates quantization of energy, wave-particle duality, the uncertainty principle, and their relationship to chemical processes. Quantum chemistry - the mathematical description of the motion and interaction of subatomic particles. It includes topics like adsorption, heterogeneous catalysis, formation of colloids, corrosion, electrode processes, and chromatography.Ĭhemical kinetics - the study of the rates of chemical reactions, the factors affecting those rates, and the mechanism by which the reactions proceed. Surface chemistry - the study of chemical reactions at surfaces of substances. Photochemistry - the study of the chemical changes caused by light. Sub-branches of physical chemistry include:

Physical chemists typically study the rate of a chemical reaction, the interaction of molecules with radiation, and the calculation of structures and properties. Physical Chemistry -the study of the effect of chemical structure on the physical properties of a substance.

Solid-state chemistry - the study of the synthesis, structure, and properties of solid materials.Īnalytical chemistry involves the qualitative and quantitative determination of the chemical components of substances.Įxamples of areas using analytical chemistry include:įorensic chemistry - the application of chemical principles, techniques, and methods to the investigation of crime.Įnvironmental chemistry -the study of the chemical and biochemical phenomena that occur in the environment.It relies heavily on analytical chemistry and includes atmospheric, aquatic, and soil chemistry.īioanalytical Chemistry - the examination of biological materials such as blood, urine, hair, saliva, and sweat to detect the presence of specific drugs. Organometallic chemistry - the study of chemical compounds containing bonds between carbon and a metal. Nuclear chemistry - the study of radioactive substances. Geochemistry - the study of the chemical composition and changes in rocks, minerals, and atmosphere of the earth or a celestial body. Inorganic chemists study things such as crystal structures, minerals, metals, catalysts, and most elements in the Periodic Table.īioinorganic chemistry - the study of the interaction of metal ions with living tissue, mainly through their direct effect on enzyme activity. It covers all chemical compounds except organic compounds. Inorganic chemistry is the study of the properties and behaviour of inorganic compounds. Stereochemistry - the study of the spatial arrangements of atoms in molecules and their effects on the chemical and physical properties of substances.Physical organic chemistry - the study of the interrelationships between structure and reactivity in organic molecules.Polymer chemistry - the study of the chemistry of polymers.Organometallic chemistry - the study of chemical compounds containing bonds between carbon and a metal.It overlaps with pharmacology (the study of drug action). Medicinal chemistry -the design, development, and synthesis of medicinal drugs.Organic chemistry overlaps with many areas including Organic chemistry involves the study of the structure, properties, and preparation of chemical compounds that consist primarily of carbon and hydrogen.
