Free radicals are molecules with an unpaired electron.
Many of the chemicals used in making medicines, plastics, and weed killers are made from anilines, molecules with an aromatic ring and amino group.
Whenever a solution contains molecules with an electropositive hydrogen atom and with an electronegative atom (such as nitrogen, oxygen, sulfur, or fluorine), hydrogen bonding may occur and, when it does, the properties of the solution are affected profoundly.
Immediately above is the Maillard zone, where heat causes reactions among sugars and proteins that turn the meat brown, yielding molecules with an intrinsically appealing flavor — at least to most humans.
Furthermore, only active molecules with an IC50 value are accounted for.
Polyketides represent a class of natural product small molecules with an impressive range of medicinal activities.
For the same reason, molecules with an MMFF94 s unparameterized element type (e.g., hyper-valent species) were removed.
Ionic CM are molecules with an electrical charge and solutions in water contain cations such as sodium or meglumine.
The increasingly negative energies signify greater interactions between the coal and CO2 molecules with an increasing pressure.
Each Ti atom can bind up to six hydrogen molecules with an average adsorption energy of 0.22 eV/H2.
The heavy-atom count (HAC) profile showed that FragranceDB comprised mostly fragment-sized [45] organic molecules with an upper boundary at approximately 21 atoms (Figure 1A).
