4.5 Molecular weight The molecular weight (formula weight) of a compound is the sum of the atomic weights of all the atoms in a molecule and can be determined by a variety of methods. Crude oil, being a complex mixture of (at least) several thousand constituents requires qualification of th...
In fact, in practice air is a mixture of all elements and compounds because everything will evaporate in air until the partial pressure of its atoms, or molecules, achieves its saturated vapour pressure. In reality, this evaporation can usually be neglected, except in the case of water. ...
P. et al. High-resolution analysis of DNA regulatory elements by synthetic saturation mutagenesis. Nat. Biotechnol. 27, 1173–1175 (2009). This article describes a method for high-throughput analysis of all possible point mutations in regulatory elements using massively parallel DNA synthesis and ...

Furthermore, all dsx genes identified in this study showed male-biased expression levels, yet only half of the putative 5’ upstream regulatory elements are preserved in D. magna and D. pulex. Conclusions The all dsx genes of five cladoceran species examined had similar amino acid structure ...

(NMR)to explore and confirm the connectivity of the atoms in the molecule.Elemental analysismethods such as Inductive coupled plasma spectroscopy (ICP-OES) effectively help to determine the elements present in the chemical compound in question. Often the combination of information from these multiple ...

1.9.1 Molecular Weight A polymer's molecular weight is the sum of the atomic weights of individual atoms that comprise a molecule. It indicates the average length of the bulk resin's polymer chains. All polymer molecules of a particular grade do not have exactly same molecular weight. There ...
Smaller-scale motions, including the behavior of gating elements and binding and translocation of smaller species such as ions and the substrate, can nowadays be effectively described using equilibrium simulations on the order of hundreds of nanoseconds. Larger, slower motions, such as structural ...
