One of the forces driving phospholipid aggregation are Vender Waals interaction. Aggregation of phospholipid molecules is favored by higher entropy of water molecules in the aggregated state. Fluidity of phospholipid membranes is lower with higher content of unsaturated fatty acids. Phospholipid membrane containing unnatural trans unsaturated fatty acid are more rigid.arrow_forward
