(chemistry) any reaction, typically involving organic compounds, in which a cyclic transition state is involved

that reacts or responds to a stimulus / (chemistry) that readily takes part in reactions / (electronics) Characterized by induction or capacitance rather than resistance.

(chemistry) any reaction in which two (or more) molecules react with the resulting loss of a molecule of water (or other small molecule); the formal reverse of hydrolysis

(organic chemistry) The condensation reaction of an amino acid and a reducing sugar, followed by polymerization to form brown pigments - melanoidins; one of the causes of browning during cooking.

(physics) Any device in which a controlled chain reaction is maintained for the purpose of creating heat (for power generation) or for creating neutrons and other fission products for experimental, medical or other purposes.

(chemistry) the reaction of a halogen with a methyl-ketone to form a haloform

(pharmacy, medicine) A reaction to a medication that is unusual and unpredictable, specific to a particular person. Unlike allergy, it can occur on first exposure to the medication; unlike a side effect, it affects only very few individuals.
