Final answer:
Simple triglycerides have three identical fatty acid side chains.
Step-by-step explanation:
Simple triglycerides have three identical fatty acid side chains.
Triglycerides are composed of a glycerol molecule attached to three fatty acids through a process called dehydration synthesis.
Each fatty acid is joined to the glycerol molecule by a covalent bond.
The fatty acids can vary in length but in a simple triglyceride, all three fatty acid side chains are identical.
