Synthetic musk - Wikipedia
Synthetic musks in a narrower sense are chemicals modeled after the main odorants in animal musk: muscone in deer musk, and civetone in civet. Muscone and civetone are macrocyclic ketones. Other structurally distinct compounds with similar odors are also known as musks.

3.4. Isomers | Organic Chemistry 1: An open textbook - Lumen …
Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space. Consider butane: There are also endless other possible ways that this molecule could twist itself. There is almost completely …
1.4: Representing structures - Chemistry LibreTexts
Chemical structures are usually represented by the skeletal formula, which provides a graphical representation of the molecule with most hydrogens omitted for clarity. Full Lewis structures are used only rarely, when a more complete drawing is needed, because they are often harder to read than skeletal structures.
26.5: Alkenes and Alkynes - Chemistry LibreTexts
2023年7月12日 — There is free rotation about the carbon-to-carbon single bonds (C–C) in alkanes. In contrast, the structure of alkenes requires that the carbon atoms of a double bond and the two atoms bonded to each carbon atom all lie in a single plane, and that each doubly bonded carbon atom lies in the center of a triangle.
Alkene - Wikipedia
Alkenes are generally colorless non-polar compounds, somewhat similar to alkanes but more reactive. The first few members of the series are gases or liquids at room temperature. The simplest alkene, ethylene (C2H4) (or "ethene" in the IUPAC nomenclature) is the organic compound produced on the largest scale industrially. [5]

1.12: Drawing Chemical Structures - Chemistry LibreTexts
2015年5月3日 — The three different ways to draw organic molecules include Kekulé Formulas, Condensed Formulas, and Skeletal structures (also called line-bond structures or line formulas). During this course, you will view molecules written in all three forms.
Holliday junction - Wikipedia
A Holliday junction is a branched nucleic acid structure that contains four double-stranded arms joined. These arms may adopt one of several conformations depending on buffer salt concentrations and the sequence of nucleobases closest to the junction. The structure is named after Robin Holliday, the molecular biologist who proposed its ...
