Summary Introduction

The reason behind phospholipids being the constituents of cell membranes and not of
Introduction:
The main constituents of cell membranes are phospholipids. They have both hydrophobic regions as well as hydrophilic regions. The head of phospholipids are hydrophilic, which have choline, phosphate, and glycero, lhereas the hydrophobics have fatty acids.

Explain why the structure of phospholipids enables them to form lipid bilayers in aqueous conditions, whereas triacylglycerols and diacylglycerols do not.
Glycolipids are nonionic lipids that can orient themselves unto bilayers as phospholipids do. They accomplish this feat without an ionic head group like that of the phospholipids. Suggest a reason why this is possible.
Phospholipids have two fatty acyl chains and can form spherical micells in the presence of water.
