Study Notes
Fatty Acids
- Omega-3 fatty acids have carbon atoms in series like 2, 4, 6.
Saturated Fatty Acids
- The molecular formula for saturated fatty acids is CnH2n+2.
- Saturated fatty acids have a hydrocarbon chain with no double bonds.
Odd Chain Fatty Acids
- Odd chain fatty acids are commonly found in ruminant fat and some microbial lipids.
Free Fatty Acids
- Free fatty acids formed in the human body during metabolism are acidic in nature.
Even Carbon Acids
- The common feature of even carbon acids is that they have an even number of carbon atoms.
Designating Double Bonds
- The Δ (delta) system is widely used by nutritionists to designate the position of double bonds in fatty acids.
Monoenoic Fatty Acids
- Monoenoic or monounsaturated fatty acids are characterized by having a single double bond in their hydrocarbon chain.
Naming System for Fatty Acids
- The Δ (delta) naming system represents the position of a double bond between carbon atoms 9 and 10 in a C18 fatty acid as Δ⁹.
Essential Fatty Acids
- The common feature of essential fatty acids is that they cannot be synthesized by the human body and must be obtained through the diet.
Learn about derived lipids which are the products obtained after the hydrolysis of simple and compound lipids, including fatty acids, alcohols, steroids, cholesterol, lipid-soluble vitamins, hormones, and ketone bodies. Understand the characteristics and components of these derived lipids.
