Which fatty acid configuration leads to the most fluid membrane?

A. Long, saturated chains
B. Short, saturated chains
C. Short, unsaturated chains
✓
D. Long, unsaturated chains

📝 Explanation

Shorter chains decrease van der Waals interactions, and double bonds create fluidity; this combination results in the highest fluidity.

📖 Additional Information
