Triacylglycerols
Multiple Choice
Draw the structure of a triacylglycerol that contains all 18:0 fatty acids. Is this a simple or mixed triacylglycerol?
A
Simple triacylglycerol.
B
Mixed triacylglycerol.
Verified step by step guidance1
Understand the structure of a triacylglycerol: It consists of a glycerol backbone esterified with three fatty acid chains.
Identify the fatty acid type: 18:0 indicates a saturated fatty acid with 18 carbon atoms and no double bonds, known as stearic acid.
Draw the glycerol backbone: Glycerol is a three-carbon molecule with hydroxyl groups (-OH) attached to each carbon.
Attach the fatty acids: Esterify each hydroxyl group of the glycerol with a stearic acid molecule, forming ester bonds.
Determine the type of triacylglycerol: Since all three fatty acids are the same (stearic acid), this is a simple triacylglycerol.
