Currently, natural gas is industrially converted to syngas by steam reforming reaction, which then can be converted either to liquid fuel by Fisher-Tropsch (F-T) process directly [1] or to methanol using Cu/ZnO/Al2O3 catalyst [2].
Among them, solar energy is the most promising energy source, because it can be converted either to electricity by photovoltaics or concentrating power plants, or to thermal energy by solar thermal collectors (flat or concentrating) [5, 6].
For presentation, the Ct values (log2) were converted either to a log10 or linear scale.
Throughout the world, grasslands are being converted either to croplands or desertified shrublands from overgrazing by livestock [6], [7].
The first branch point in the fructose uptake pathway is fructose 1-phosphate (F1P), which can be converted either to fructose 1,6-bisphosphate (FBP) or to DHAP and glyceraldehyde (GA).
The allylic alcohol 37 was converted either to ethyl phosphonate 39 by using a standard two-step Appel 29/Arbuzov 30 procedure, or directly by a Mitsunobu 31 reaction to afford a variety of sulfides (40 a– c) (Scheme 8).
Thus oxidation of fatty acids by astroglial mitochondria provides energy and part of the carbon skeleton for the anaplerotic synthesis of neuromediators and saves glucose, which is converted either into lactate to fuel neurons, or stored for emergency as glycogen.
Furthermore, the type I citrullinemia model was able to utilize partially the urea cycle by synthesizing ornithine, which was then converted either to glutamate by the ornithine transaminase (E.C.2.6.1.13) or to citrulline by the ornithine carbamoyltransferase (E.C. 2.1.3.3).
HP can be further converted either to 5-hydroxyeicosatetraenoic acid (HT) by glutathione peroxidase (GPx) [ 7, 8].
