glucose 6-phosphate g6p, sometimes called the robison ester is a glucose sugar phosphorylated at the hydroxy group on carbon 6. this dianion is very common in cells as the majority of glucose entering a cell will become phosphorylated in this way.. because of its prominent position in cellular chemistry, glucose 6-phosphate has many possible fates within the cell.
carbohydrate metabolism is the whole of the biochemical processes responsible for the metabolic formation, breakdown, and interconversion of carbohydrates in living organisms.. carbohydrates are central to many essential metabolic pathways. plants synthesize carbohydrates from carbon dioxide and water through photosynthesis, allowing them to store energy absorbed from sunlight internally.
the dna double helix is stabilized primarily by two forces: hydrogen bonds between nucleotides and base-stacking interactions among aromatic nucleobases. the four bases found in dna are adenine a , cytosine c , guanine g and thymine t . these four bases are attached to the sugar-phosphate to form the complete nucleotide, as shown for adenosine monophosphate.
astronomers report that the usual hubble classification, particularly concerning spiral galaxies, may not be supported, and may need updating. researchers at the university of colorado boulder demonstrate 'nanobio-hybrid' organisms capable of using airborne carbon dioxide and nitrogen to produce a variety of eco-friendly plastics and fuels.
indium phosphide inp is used to produce efficient lasers, sensitive photodetectors and modulators in the wavelength window typically used for telecommunications, i.e., 1550 nm wavelengths, as it is a direct bandgap iii-v compound semiconductor material. the wavelength between about 1510 nm and 1600 nm has the lowest attenuation available on .
the conversion of d-glucose-6-phosphate to d-fructose-6-phosphate is catalyzed by glucose-6-phosphate isomerase, an intramolecular oxidoreductase. the overall reaction involves the opening of the ring to form an aldose via acid/base catalysis and the subsequent formation of a cis-endiol intermediate. a ketose is then formed and the ring is .
a plug-in hybrid electric vehicle phev is a hybrid electric vehicle whose battery can be recharged by plugging it into an external source of electric power, as well as by its on-board engine and generator.most phevs are passenger cars, but there are also phev versions of commercial vehicles and vans, utility trucks, buses, trains, motorcycles, scooters, and military vehicles.
chlorella is a genus of single-celled green algae belonging to the division chlorophyta.it is spherical in shape, about 2 to 10 μm in diameter, and is without flagella.it contains the green photosynthetic pigments chlorophyll-a and -b in its chloroplast.in ideal conditions it multiplies rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.
in biochemistry, a metabolic pathway is a linked series of chemical reactions occurring within a cell.the reactants, products, and intermediates of an enzymatic reaction are known as metabolites, which are modified by a sequence of chemical reactions catalyzed by enzymes.: 26 in most cases of a metabolic pathway, the product of one enzyme acts as the substrate for the next.
phosphine iupac name: phosphane is the compound with the chemical formula ph 3. it is a colorless, flammable, toxic gas and is classed as a pnictogen hydride. pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane p 2 h 4 .
triose phosphate isomerase is a dimer of identical subunits, each of which is made up of about 250 amino acid residues. the three-dimensional structure of a subunit contains eight α-helices on the outside and eight parallel β-strands on the inside. in the illustration, the ribbon backbone of each subunit is colored in blue to red from n-terminus to c-terminus.
