Reagent :: Reagent (n.) A substance capable of producing with another a reaction, especially when employed to detect the presence of other bodies; a test..

Rational :: Rational (a.) Expressing the type, structure, relations, and reactions of a compound; graphic; -- said of formulae. See under Formula..

Coagulate :: Coagulate (v. t.) To cause (a liquid) to change into a curdlike or semisolid state, not by evaporation but by some kind of chemical reaction; to curdle; as, rennet coagulates milk; heat coagulates the white of an egg..

Magnesia :: Magnesia (n.) A light earthy white substance, consisting of magnesium oxide, and obtained by heating magnesium hydrate or carbonate, or by burning magnesium. It has a slightly alkaline reaction, and is used in medicine as a mild antacid laxative. See Magnesium..

Electro-muscular :: Electro-muscular (a.) Pertaining the reaction (contraction) of the muscles under electricity, or their sensibility to it..

Synthesis :: Synthesis (n.) The art or process of making a compound by putting the ingredients together, as contrasted with analysis; thus, water is made by synthesis from hydrogen and oxygen; hence, specifically, the building up of complex compounds by special reactions, whereby their component radicals are so grouped that the resulting substances are identical in every respect with the natural articles when such occur; thus, artificial alcohol, urea, indigo blue, alizarin, etc., are made by synthesis..

Reaction :: Reaction (n.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.

Lactucin :: Lactucin (n.) A white, crystalline substance, having a bitter taste and a neutral reaction, and forming one of the essential ingredients of lactucarium..

Turbine :: Turbine (n.) A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel..

Coagulation :: Coagulation (n.) The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification..

Catalysis :: Catalysis (n.) A process by which reaction occurs in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyali

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

Xanthoproteic :: Xanthoproteic (a.) Pertaining to, or derived from, xanthoprotein; showing the characters of xanthoprotein; as, xanthoproteic acid; the xanthoproteic reaction for albumin..

Antiperistasis :: Antiperistasis (n.) Opposition by which the quality opposed asquires strength; resistance or reaction roused by opposition or by the action of an opposite principle or quality.

Explosive :: Explosive (n.) An explosive agent; a compound or mixture susceptible of a rapid chemical reaction, as gunpowder, or nitro-glycerine..

Reflux :: Reflux (n.) A flowing back, as the return of a fluid; ebb; reaction; as, the flux and reflux of the tides..

Revulsion :: Revulsion (n.) A sudden reaction; a sudden and complete change; -- applied to the feelings.

Preaction :: Preaction (n.) Previous action.

Protamin :: Protamin (n.) An amorphous nitrogenous substance found in the spermatic fluid of salmon. It is soluble in water, which an alkaline reaction, and unites with acids and metallic bases..

Basic :: Basic (a.) Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper..
