Fatty lipids and acids
Cards in this deck (21)
- 1Describe saturated fatty acidsIt has no double bond.
Completely saturated in hydrogen bonds. - 2Oleic Acid
- 3Is an Oleic Acid saturated, monounsaturated and polyunsaturated? Why?Monounsaturated because it has 1 double bond
- 4Caproic Acid
- 5Is a Caproic Acid saturated, monounsaturated and polyunsaturated? Why?Saturated because there are no double bonds
- 6Linolenic Acid
- 7Is a Linolenic Acid saturated, monounsaturated and polyunsaturatedPolyunsaturated because it has 3 double bonds
- 8Cis-isomers Structural Diagram
- 9Trans-ismors Structural Diagram
- 10Are Cis-isomers natural or synthesised?Very common in nature
- 11Are Trans-isomers natural or synthesised?Rare in nature - usually artificially produced (make solid fats)
- 12Positioning of the hydrogen atoms in Cis-isomersOn the same side of the 2 carbon atoms
- 13Positioning of the hydrogen atoms in Trans-isomersOn different sides of the 2 carbon atoms
- 14Shape of the Cis-isomers fatty acid chainThe double bonds causes a bend in the fatty acid chain
- 15Shape of the Trans-isomers fatty acid chainThe double bond doesn't cause a bend in the fatty acid chain
- 16Density of fatty acids in cis-isomersLoosely packed
- 17Density of fatty acids in trans-isomersClosely packed
- 18Are Triglycerides formed from cis-isomers solid or liquids at room temperature?They have low melting points - they are usually liquid at room temperature
- 19Are Triglycerides formed from trans-isomers solid or liquids at room temperature?They have high melting points - they are usually solid at room temperature
- 20Identify whether this isomer is cis or trans. Why?Trans-Oleic Acid
Because the double bond does not cause a bend in the chain
- 21Identify whether this isomer is cis or trans. Why?Cis-Oleic Acid
Because the double bond causes a bend in the chain
