Quiz zum Vortrag
Which of the following is true regarding the melting temperature of fatty acids?
- it is lower for essential fatty acids than a fatty acid with one double bond.
- It increases as saturation decreases.
- It decreases as saturation increases.
- It increases as unsaturation increases.
- A saturated fatty acid with 18 carbons has a lower melting point than an unsaturated fatty acid with 18 carbons.
Why does linolenic acid have a lower melting temperature than stearic acid even though both have 18 carbon chain lengths?
- The increase in unsaturation in the fatty acids leads to a reduction in melting temperatures.
- The increase in saturation in the fatty acids leads to a reduction in melting temperatures.
- The increase in single bonds in the fatty acids leads to a reduction in melting temperatures.
- The increase in double bonds in the fatty acids leads to an increase in melting temperatures.
- The increase in triple bonds in the fatty acids leads to an increase in melting temperatures.
Which of the following statement is not true?
- Animal cells can form double bonds at positions 12 and 15 in the fatty acids.
- The increase in the chain lengths leads to an increase in the melting temperatures for saturated fatty acids.
- The delta numbering system and omega numbering system are used to determine the positions of double bonds in the fatty acids.
- The omega-3 fatty acids are considered good fatty acids for the health of the heart.
- The omega numbering system starts numbering the carbons from the methyl group.
