Study Notes
Lipids
- The most abundant lipid in nature is triglycerides.
- A simple triglyceride is a type of triglyceride that has three fatty acids connected to glycerol of the same type.
- Hydrolysis is the process that results in the production of monoglyceride.
- The main difference between fats and oils is that fats are solid at room temperature, while oils are liquid.
- The chemical property that allows fats to float on water is their non-polar and hydrophobic nature.
Fatty Acids
- The systematic name for a C18 fatty acid with no double bonds is stearic acid.
- The notation 18:2 signifies that a fatty acid has 18 carbon atoms and 2 double bonds.
- When counting from the distal end, with the ω-carbon as number 1, the position of a double bond is represented by the symbol ω (omega) followed by a number.
- The position of a double bond can also be represented by the symbol ∆ (delta) followed by a superscript number.
- The α, β, and ω-carbons in a fatty acid are the carbon atoms that are closest to the carboxyl group, next to the α-carbon, and at the end of the fatty acid chain, respectively.
Fatty Acid Structure
- The systematic name for a C18 fatty acid with two double bonds is linoleic acid.
- The notation 18:0 signifies that a fatty acid has 18 carbon atoms and no double bonds.
- The systematic name for a C16 fatty acid with no double bonds is palmitic acid.
Fats and Waxes
- The main difference between fats and waxes is that fats are esters of glycerol, while waxes are esters of long-chain fatty acids and long-chain alcohols.
- A mixed triglyceride is a type of triglyceride that has three fatty acids connected to glycerol of different types.
- The chemical property that allows fats to be insoluble in water but soluble in organic solvents like ether and benzene is their non-polar and hydrophobic nature.
- Lipolysis is the process that results in the production of diglyceride.
