Study Notes
• The video discusses the nomenclature of fatty acids, including their common and systematic names.
• Fatty acids are a diverse group of compounds, represented by the general formula R-COOH, where R is a hydrocarbon chain with a certain length.
• Fatty acids exist in our body, mainly in the form of esters in fats, such as triglycerides, and can also be found in natural oils, like olive oil.
• Non-esterified fatty acids are also known as free fatty acids (FFA) or acylglycerides.
• Fatty acids in natural fats usually have an even number of carbon atoms and a linear chain of carbon atoms that can be saturated (without double bonds) or unsaturated (with one or more double bonds).
• The nomenclature of fatty acids is based on the hydrocarbon chain, with the suffix "-oic" added to the end of the name.
• For example, a saturated fatty acid with 18 carbon atoms is named octadecanoic acid, and an unsaturated fatty acid with 18 carbon atoms and a double bond at the 9th carbon atom is named 9-octadecenoic acid.
• The location of double bonds is indicated by the carbon atom number, and multiple double bonds are separated by commas.
• The video provides a table summarizing the systematic names of fatty acids with different numbers of carbon atoms, from 4 to 20.
• The table also includes examples of unsaturated fatty acids with one, two, or three double bonds.
• The video also discusses the common names of fatty acids, which are often derived from their origin, such as palmitic acid (from palm oil) and stearic acid (from animal fat).
• The common names of fatty acids can be ionized to form carboxylates, such as palmitate and stearate.
• The video provides a downloadable PDF file with a summary of the nomenclature rules and examples for each type of fatty acid.
Learn about the naming conventions of fatty acids, including their systematic and common names, as well as their structures and properties. Understand how to identify and classify different types of fatty acids, including saturated and unsaturated fatty acids. Explore the rules and examples of fatty acid nomenclature.
