| Describe saturated fatty acids | It has no double bond. Completely saturated in hydrogen bonds. |
| Oleic Acid | |
| Is an Oleic Acid saturated, monounsaturated and polyunsaturated? Why? | Monounsaturated because it has 1 double bond |
| Caproic Acid | |
| Is a Caproic Acid saturated, monounsaturated and polyunsaturated? Why? | Saturated because there are no double bonds |
| Linolenic Acid | |
| Is a Linolenic Acid saturated, monounsaturated and polyunsaturated | Polyunsaturated because it has 3 double bonds |
| Cis-isomers Structural Diagram | |
| Trans-ismors Structural Diagram | |
| Are Cis-isomers natural or synthesised? | Very common in nature |
| Are Trans-isomers natural or synthesised? | Rare in nature - usually artificially produced (make solid fats) |
| Positioning of the hydrogen atoms in Cis-isomers | On the same side of the 2 carbon atoms |
| Positioning of the hydrogen atoms in Trans-isomers | On different sides of the 2 carbon atoms |
| Shape of the Cis-isomers fatty acid chain | The double bonds causes a bend in the fatty acid chain |
| Shape of the Trans-isomers fatty acid chain | The double bond doesn't cause a bend in the fatty acid chain |
| Density of fatty acids in cis-isomers | Loosely packed |
| Density of fatty acids in trans-isomers | Closely packed |
| Are Triglycerides formed from cis-isomers solid or liquids at room temperature? | They have low melting points - they are usually liquid at room temperature |
| Are Triglycerides formed from trans-isomers solid or liquids at room temperature? | They have high melting points - they are usually solid at room temperature |
| Identify whether this isomer is cis or trans. Why? | Trans-Oleic Acid Because the double bond does not cause a bend in the chain |
| Identify whether this isomer is cis or trans. Why? | Cis-Oleic Acid Because the double bond causes a bend in the chain |
