Summary
Wikipedia’s molecular entries offer a diverse chemical perspective. Public interest, shown by pageviews, centers on drugs and culturally relevant molecules, not industrial chemicals.
Area of Science:
- Chemistry
- Information Science
- Public Knowledge
Background:
- Wikipedia is a globally prominent information source with extensive molecular data.
- The chemical content and public perception of Wikipedia's molecular entries remain understudied.
Purpose of the Study:
- To systematically analyze Wikipedia's molecular entries for use, structural diversity, and public interest.
- To provide an overview of the roles and applications of chemical compounds documented on Wikipedia.
Main Methods:
- Classification of molecular entries into use categories.
- Scaffold analysis and Uniform Manifold Approximation and Projection (UMAP) for structural diversity.
- Analysis of Wikipedia pageview statistics to gauge public interest.
Main Results:
- Identified diverse chemical classes and applications within Wikipedia's molecular entries.
- UMAP visualization revealed distinct clusters for major chemical groups.
- Pageview data indicated high public interest in CNS-active drugs, recreational substances, and medically/culturally relevant molecules.
- Industrial and specialty chemicals received significantly less attention.
Conclusions:
- Wikipedia serves as a chemically diverse and socially informative resource on molecules.
- Public engagement with molecular information on Wikipedia reflects societal interests and priorities.
- This study highlights Wikipedia's unique position at the intersection of chemistry, open data, and public knowledge.

02:58Chemistry of the Cell
37.2K
The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...

02:08Introduction to Functional Groups
26.3K
Functional groups are group of atoms with specific chemical properties that occur within organic molecules and sometimes denoted as “R”. Functional groups are found along the carbon backbone of macromolecules can form chains or rings of carbon atoms. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.

01:01Polymers: Defining Molecular Weight
3.0K
Unlike small molecules with definite molecular weights, polymers are a mixture of individual polymer chains of varying lengths, each with a unique molecular weight. So, the molecular weight of a polymer is expressed as an average value based on the average size of the polymer chains. The two most common forms of averages used for polymers are the number average molecular weight and weight average molecular weight.

01:10Polymers: Molecular Weight Distribution
4.0K
For any given polymer, the weight average molecular weight (Mw) is higher than, if not equal to, the number average molecular weight (Mn). The only situation in which the weight average molecular weight and the number average molecular weight are equal is when a polymer consists only of chains with equal molecular weight. However, this never happens in a synthetic polymer, since it is difficult to control the polymerization process up to a molecular level with accuracy to a hundred percent.
