Chapter 23, Problem 88
Draw the structure of glycerol myristate, a fat made from glycerol and three myristic acid molecules (see Table 23.3).
Verified step by step guidance1
Step 1: Understand the components involved. Glycerol is a triol, meaning it has three hydroxyl (OH) groups. Myristic acid is a saturated fatty acid with the chemical formula C14H28O2.
Step 2: Recognize the esterification process. Glycerol myristate is formed by the esterification of glycerol with three myristic acid molecules. Each hydroxyl group of glycerol reacts with the carboxyl group of a myristic acid molecule, releasing water and forming an ester bond.
Step 3: Draw the glycerol backbone. Start by drawing the three-carbon chain of glycerol, with each carbon atom bonded to a hydroxyl group.
Step 4: Attach the myristic acid chains. For each hydroxyl group on the glycerol, draw an ester linkage to a myristic acid chain. This involves connecting the oxygen of the hydroxyl group to the carbonyl carbon of the myristic acid, forming an ester bond.
Step 5: Complete the structure. Ensure that each myristic acid chain is fully drawn, showing the 14-carbon saturated chain attached to the glycerol backbone through the ester linkage.
