CompoundDescription
hydronium ion
NADH
CopperA heavy metal trace element with the atomic symbol Cu, atomic number 29, and atomic weight 63.55.
carbon monoxideCarbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
Flavin MononucleotideA coenzyme for a number of oxidative enzymes including NADH DEHYDROGENASE. It is the principal form in which RIBOFLAVIN is found in cells and tissues.
ubiquinol 1
coenzyme q10Ubiquinone ring with a chain of 10 isoprene units; redox equilibrium with ubiqunol serving in mitochondrial inner membrane to transfer electrons; presence during reconstitution of acetylcholine receptor into phospholipid vesicles yields vesicles active in catalyzing carbamylcholine-sensitive Na+ flux; coenzyme Q10 depletion has been noted with use of statins
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.
1,5-dihydro-FADchromophore component of E coli DNA photolyase
adenosine monophosphateAdenine nucleotide containing one phosphate group esterified to the sugar moiety in the 2'-, 3'-, or 5'-position.
nadA coenzyme composed of ribosylnicotinamide 5'-diphosphate coupled to adenosine 5'-phosphate by pyrophosphate linkage. It is found widely in nature and is involved in numerous enzymatic reactions in which it serves as an electron carrier by being alternately oxidized (NAD+) and reduced (NADH). (Dorland, 27th ed)
Flavin-Adenine DinucleotideA condensation product of riboflavin and adenosine diphosphate. The coenzyme of various aerobic dehydrogenases, e.g., D-amino acid oxidase and L-amino acid oxidase. (Lehninger, Principles of Biochemistry, 1982, p972)
