Enzymes: Nature's Factory Workers
What are enzymes? Why they're nature's little factory workers. They chop up certain things! They build up others! Pretty amazing the kind of chemistry nature can do given enormous polypeptide chains with unfathomable variability and...

Cleavage of Carbon-Carbon Bonds With Periodic Acid
Just as important as learning reactions that generate carbon-carbon bonds, we need ways to cleave carbon-carbon bonds as well.This is useful for splitting a molecule up into fragments, or transforming a cyclic molecule into a linear...

Protein Structure
Everyone has heard of proteins. What are they on the molecular level? They're polymers of amino acids, of course. They make up most of your body, so we have to understand their structure very well! Check this out to learn the hierarchy...

Friedel Crafts Acylation
Sal describes the mechanism for creating a ketone, starting with benzene and acetyl chloride. Electrophilic aromatic substitution is similar. Viewers will find that prior helpful knowledge. Acylation of a benzene ring in the presence of...

Ketone Naming, Aldehydes and Ketones, Organic chemistry
Starting with the distinctions between Ketones and Aldehydes, Sal diagrams the groups that affect the naming.
Khan Academy
Alcohols, Alcohols, Ethers, Epoxides, Sulfides, Organic chemistry
Sal approaches the functional group OH. He gives details of the term alcohol and clarifies the differences from drinking alcohol. Again, there is practice in naming molecules and identifying the location of functional groups.
