Stimulation, Photic,Visual Stimulation,Photic Stimulations,Stimulation, Visual,Stimulations, Photic,Stimulations, Visual,Visual Stimulations
D010782 Photolysis Chemical bond cleavage reactions resulting from absorption of radiant energy. Photodegradation
D011407 Propane A three carbon alkane with the formula H3CCH2CH3.
D011743 Pyrimidines A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They include several nucleic acid constituents (CYTOSINE; THYMINE; and URACIL) and form the basic structure of the barbiturates.
D002621 Chemistry A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
D002845 Chromatography Techniques used to separate mixtures of substances based on differences in the relative affinities of the substances for mobile and stationary phases. A mobile phase (fluid or gas) passes through a column containing a stationary phase of porous solid or liquid coated on a solid support. Usage is both analytical for small amounts and preparative for bulk amounts. Chromatographies
D003503 Cyclobutanes Four carbon cycloparaffin cyclobutane (the structural formula (CH2)4) and its derivatives.
D003640 Dealkylation The removing of alkyl groups from a compound. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed) Dealkylations
D006868 Hydrolysis The process of cleaving a chemical compound by the addition of a molecule of water.
