Magazine Chapter 15: Q. 15.24 (page 521)
Linoleic acid is an -carbon unsaturated fatty acid with two double bonds that occur in many vegetable oils including safflower oil and poppyseed oil . Draw the line-angle formula for glyceryl trilinoleate (trilinolein).
Short Answer
Expert verified
Linoleic acid is an unsaturated fatty acid with 18 carbons that can be found in a variety of vegetable oils, including sunflower and poppy seed oil.
Step by step solution
01
Introduction
- Lipids are hydrophobic esters of intermediate to long-chain fatty acids.
- Saturated and unsaturated fatty acids are the two forms of fatty acids.
- Unsaturated fatty acids have a long chain of carboxylic acids with double or triple bonds in their structure.
- The fatty acid chain is said to be saturated when it contains all of the single bonds in its structure.
02
Explanation
- Fats, waxes, sterols, and triglycerides are examples of naturally occurring lipids.
- Triglycerides are lipids that have glycerol linked to three fatty acids.
- Fats and oils are examples of triglycerides.
- Long, unbranched carbon chains with a carboxylic acid group at one end make up fatty acids.
- Unsaturated fatty acids have one or more carbon-carbon double bonds, whereas saturated fatty acids have only single carbon-carbon bonds.
03
Determine the line-angle formula for glyceryl trilinoleate (trilinolein).
- Sunflower oil and poppy seed oil contain linoleic acid, an unsaturated fatty acid with 18 carbons.
- Glyceryl trilinoleate (trilinolein) has the following line-angle formula:
