How do lipids form cell membranes

WebLipids are a diverse group of compounds that are united by a common feature. Lipids are hydrophobic (“water-fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long … WebApr 8, 2024 · The lipids in cell membranes have already been discussed. Now, let us check their physical and chemical features. As they have a dual feature, when the dry membrane lipids and cholesterols are mixed in an aqueous solution, the molecules show an excellent property. This is where the molecules form micelles.
