-
- "Omega-3 unsaturated fatty acid, alpha-linolenic"
- Have a double bond near the CH3 end of the aliphatic chain
-
- "Omega-6 unsaturated fatty acid, gamma-linolenic"
- Have a double bond 6 carbons in from the CH3 end of the aliphatic chain
-
- "Linseed oil is the most common industrial drying oil"
- Because of its ability to polymerize into a hard film if applied as a thin layer on a surface (paint)
-
- "Saturated fatty acid structure"
- Saturated fatty acids are structurally zigzeg, but linear overall
- In nature, FAs tend to be even numbered
-
- "Soap - has excellent emulsifying properties"
- Monovalent salts of FFAs (soap) are "water soluble" and have strong surface tension reducing properties (bubbles)
- Cannot be used as an emulsifier because of awful taste
-
- "Cis form of FA"
- The hydrogen is on the same side of the carbon double bond
- This is the form most "natural" fatty acids are found in biological systems
- A cis double bond also introduces a distinct kink into the molecular structure
- Cis unsaturated FA is not linear, has an "L" or "U" shape dependin on where the double bond is located
-
- "Cis form of FA"
- The hydrogen is on the same side of the carbon double bond
- This is the form most "natural" fatty acids are found in biological systems
- A cis double bond also introduces a distinct kink into the molecular structure
- Cis unsaturated FA is not linear, has an "L" or "U" shape dependin on where the double bond is located
-
- "Trans form of FA"
- Hydrogens next to the double bond are on the opposite side of the chain, returning the moleule to more or less a linear structure
- Has distinctly different properties than the cis form
- A single trans bond makes a FA structurally appear more like a saturated FA than an unsaturated FA
-
- "Saturated or mono-trans line up easier"
- Promotes crystallization and plastic fat formation
-
- "Mono-cis more difficult to fit tightly"
- Melt at much lower temp
-
"More realistic structure of a triglyceride"
