chemo-, chem-, chemico-, chemi-, -chemist, -chemic, -chemical +
(Arabic > Greek > Latin: the art of combining base metals [to make gold]; from Greek, chemia, “Egypt”, supposedly where the art of changing metals into gold existed)
photochemical
Referring to the chemical properties of light; chemically reactive in the presence of light or other radiation.
photochemistry
1. The branch of chemistry having to do with the effect of light, or other radiant energy, while producing a chemical action, as with photographs.
2. The scientific study of chemical changes caused, or influenced, by the effects of light.
photochemotherapy
The treatment of cancer by intravenous injection of a photosensitizing agent; such as, hematoporphyrin, followed by exposure to visible light of superficial tumors or deep tumors by a fiberotic probe.
phytochemistry, phytochemical
1. The chemistry of plants, plant processes, and plant products.
2. The chemistry of plants and their metabolic processes.
polychemotherapy
The use of several chemotherapeutic agents in a treatment schedule.
psychochemistry
The application of biochemistry to psychiatry and especially to the understanding of the neurochemical patterns that may be a fundamental part of at least some psychiatric disorders.
sonochemistry, sonochemical
1. Chemistry in which reactions occur under ultrasound.
2. Any chemical change; such as, in a reaction type or rate, that occurs in response to sound or ultrasound.
stereochemistry, stereochemical
The study of how the properties of a compound are affected by the spatial positions of groups within its molecules. Stereochemistry is also concerned with determining the structure of stereoisomers (molecules with the same atoms and bond structure, but different three dimensional arrangements of atoms).
2. The study of the spatial distribution of atoms in a compound and its effects on the compound's properties.
thermochemist
One who specializes in the use of chemical action and heat.
thermochemistry, thermochemical
1. The interrelation of chemical action and heat.
2. The aspect of physical chemistry dealing with heat changes that accompany chemical reactions and changes of state.
3. The study of chemical changes and energies as they are affected by heat.
4. The use of chemicals in treating or preventing disease; based on their effect on the causative agent.
5. A branch of chemistry studying the heat changes that accompany chemical reactions and changes of state.
zymochemistry
The chemistry of fermentation.
