DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...

Both occupational and environmental exposure to organphosphorus insecticides is primarily associated with dermal exposure; accounting for more than 90% of the absorbed dose (Aprea et al., 1994). Therefore, an understanding of the percutaneous absorption is critical for quantitatively determining a systemi...
Alkali labile phosphorus (ALP). Statistical analysis indicated a highly significant statistical effect on ALP levels related to using E2 (ANOVA;p< 0.001). However, no photoperiod, time, or factor interaction effects were observed (p> 0.05). Throughout the experiment, fish with estradiol averaged ...
Then, the z-distance between a POPC in the tunnel formed by TMD and the center of mass of the phosphorus atoms was calculated. A total of 6 bins was generated based on the distance from 10 to 16 Å, with a bin width of 1 Å, and the number of POPC was counted in each ...
Purity of the two LPI was assessed by TLC on silica gel (Merck) using chloroform/methanol/water (65/25/4, v/v/v) as a solvent after coloration with Zinzadze reagent (79) and their concentration was measured by total phosphorus determination using a modification (80) of the procedure of...
beyond F,O,N) examples of C–H⋯P interactions can be introduced during teaching the chemistry of phosphorus (Hansen, Du, & Kjaergaard, 2014). As shown above, proposing an H-bridge interaction among molecules requires expertise, critical thinking, and previous knowledge about the HBD and HB...
4and the presence of heteroatoms such as phosphorus, sulfur, oxygen, nitrogen, etc. makes them effective in a variety of acidic solutions5,6. Direct contact between the mild steel and the corrosive environment is avoided by adsorption of the organic molecules onto the metal surface7,8, however...
