WaterA clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
OxygenAn element with atomic symbol O, atomic number 8, and atomic weight [15.99903; 15.99977]. It is the most abundant element on earth and essential for respiration.
dithiothreitolA reagent commonly used in biochemical studies as a protective agent to prevent the oxidation of SH (thiol) groups and for reducing disulphides to dithiols.
antheraxanthinRN given refers to cpd without isomeric designation
violaxanthina carotene epoxide that is precursor to capsanthin; one of 3 xanthophylls involved in evolution of plastids of green plants (oxygen evolution); 3 (violaxanthin, zeaxanthin & antheraxanthin) participate in series of photo-induced interconversions known as ''violaxanthin cycle''; structure; cleavage of 9-cis-epoxycarotenoids (violaxanthin) to xanthoxin, catalyzed by 9-cis-epoxycarotenoid dioxygenase, is the key regulatory step of ABSCISIC ACID biosynthesis
