Themolecular weight(or relative molecular mass) of a substance is the mass of its molecules relative to that of other molecules. The datum formolecular weightsis carbon-12, and this is given amolecular weightof 12. All other elements and compounds have molecular weights relative to this, and ...
(Here we ignore14C, which is generally of negligible abundance compared to the other two isotopes.) The natural abundance of12C is approximately 98.9%, and the natural abundance of13C is approximately 1.1%. Some elements, such as arsenic, have only a single isotope in the naturally occurring ...
ElementKG covers the class hierarchy of elements, the chemical attributes of elements, the relationships between elements, the corresponding functional groups, and the connections between functional groups and their constituent elements. Second, we introduce an element-guided graph augmentation in ...
Neural network (NN) interatomic potentials provide fast prediction of potential energy surfaces, closely matching the accuracy of the electronic structure methods used to produce the training data. However, NN predictions are only reliable within well-le
Storage or transportation temperature is very important for preserving the quality of fruit. However, low temperature in sensitive fruit such as peach can induce loss of quality. Fruit exposed to a specific range of temperatures and for a longer period c
Moreover, some light- and pathogen-responsive cis-acting elements were also found, such as Box 4, Box-W1 and W box. 123 Mol Biol Rep Fig. 2 Alignment of the deduced GhAPm protein sequence with other plant AP complexes l subunit Analysis of the GhAPm protein structure The 3-D structure...
Molecular descriptors are widely employed to present molecular characteristics in cheminformatics. Various molecular-descriptor-calculation software programs have been developed. However, users of those programs must contend with several issues, includin
protein, lipids, minerals, and other trace elements. Among them, starch and protein are two major components of rice endosperm, accounting for approximately 80% and 10%, respectively, of the weight of milled rice (Wang et al.2020a). As the largest constituent of rice endosperm, starch ...
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 ...
a, Schematics of cedA promoter region. Arrows indicate the direction of transcription. The −10 and −35 elements of katA and cedA promoters are colored in blue and yellow, respectively. b,c, katA (b) and cedA (c) mRNA changes in response to different stress conditions as determined by...
