But once there is a double bond (i.e C18 and C18:1), the melting point drops significantly. If more than one double bond exists, the melting point drops further (C18:1 and C18:2).

PubChem atom environments | Journal of …

Atom environments and fragments find wide-spread use in chemical information and cheminformatics. They are the basis of prediction models, an integral part in similarity searching, and employed in structure search techniques. Most of these methods were developed and evaluated on the relatively small sets of chemical structures available at the time.

History of Atomic Structure | Boundless Chemistry

Dalton noted from these percentages that 100g of tin will coine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of 1:2. Dalton found an atomic theory of matter could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will coine with either one or two oxygen atoms.

Comparative evaluation of atom mapping algorithms …

An atom mapping for the enolase reaction. a Enolase (VMH ID: ENO) alyses the hydrolysis of 2-phosphoglycerate (VMH ID: 2pg) to produce phosphoenolpyruvate (VMH ID: pep) and water (VMH ID: h2o). The atoms of the substrate are assigned with a mapping nuer that matches only with one atom of the same element in the product molecules; this representation describes the reaction mechanism.

1Kg Activated Carbon 3mm Pellets - Brownell Limited

Activated Carbon is produced from materials such as lignite coal, wood and coconut shells. The chemical activation process used involves exposure to steam and oxygen. This generates a porous structure of the adsorbent material, which produces a larger surface area to attract and hold hydrocarbon vapours to its carbon atom particles.

In SEAGrid, how do I build a molecule?

In the "Nanocad" window, Shift-click near a carbon atom. A red oxygen atom will appear. To build a carbon-oxygen bond, Shift-drag from one carbon atom to the oxygen atom. Because the carbon-oxygen bond in acetaldehyde is double bond, you must repeat this process one more time. You will see a double bond between the carbon and oxygen atoms.
