Finally, the compounds attached to each reaction were added to produce a bipartite metabolic network for each species.
More and more elders from surrounding villages trek miles across rugged terrain to attend weekly shuras, or meetings, held at an Afghan police compound attached to the base.
Each strand of this molecule is a series of nucleotides, and each nucleotide is composed of a sugar-phosphate compound attached to one of four nitrogen-containing bases.
Depending on the pharmacology of a medical substance it will be excreted as a mixture of metabolites, as unchanged substance, or conjugated with an inactivating compound attached to the molecule [ 1].
Extraction of pure DNA from sources such as strawberry, which contain high amounts of phenolic compounds and polysaccharides is challenging, as the compounds tend to attach to DNA during purification and interfere with the subsequent enzymatic reactions [ 20, 21].
Here, chemical compounds called methyl groups attach to regions of DNA and, like a volume knob on a stereo, turn the activity of a gene up or down.
Once PAHs are inhaled or ingested, they are metabolized to compounds that can readily attach to DNA, forming so-called bulky DNA adducts that can set the stage for mutation and carcinogenesis.
Single-Crystal X-ray Diffraction: Single crystals of the title compounds were attached to a glass fiber by using perfluorinated oil and were mounted on a Bruker KAPPA APEX II diffractometer equipped with a CCD detector.
The results showed that the compound attaches to ATP synthase, an enzyme that makes ATP, the cell's main energy-carrying molecule.
This implies that –COOH group in the compound is attached to the gold nanoparticles and there in a clear change in the spectra.
