Phospholipid: Definition, Structure, Function - Biology Dictionary
2019年10月4日 · A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule.
Lipid bilayer - Wikipedia
The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes form a continuous barrier around all cells.
Phospholipid - Wikipedia
Phospholipids are a key component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. In eukaryotes, cell membranes also contain another class of lipid, sterol, interspersed among the phospholipids. The combination provides fluidity in two dimensions combined with mechanical strength against rupture.

2018年1月26日 · The phospholipid bilayer is the fundamental structure of the plasma membrane. We will explore its components, structure, functions, examples & all about it.
Phospholipid Bilayer- Structure, Types, Properties, Functions
2023年4月8日 · The phospholipid bilayer consists of phospholipids arranged in two layers with exterior facing hydrophilic polar heads and interior hydrophobic non-polar tails. This imparts the amphiphilic nature to phospholipids.
2.5: Phospholipid Bilayers - Biology LibreTexts
The phospholipid bilayer consists of two layers of phospholipids, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior. The hydrophilic (polar) head group and hydrophobic tails (fatty acid chains) are depicted in the single phospholipid molecule.
Lipid Bilayer - Definition, Function and Structure - Biology …
2019年4月17日 · Each lipid molecule, or phospholipid, contains a hydrophilic head and a hydrophobic tail. The tail regions, being repelled by water and slightly attracted to each other, congregate together. This exposes the head regions to the outside, creating a barrier between two bodies of water.

2024年12月2日 · phospholipid, any member of a large class of fatlike, phosphorus-containing substances that play important structural and metabolic roles in living cells.
The Lipid Bilayer - Molecular Biology of the Cell - NCBI Bookshelf
Being cylindrical, phospholipid molecules spontaneously form bilayers in aqueous environments. In this energetically most-favorable arrangement, the hydrophilic heads face the water at each surface of the bilayer, and the hydrophobic tails are shielded from the water in the interior.
14.3: Phospholipids in Cell Membranes - Chemistry LibreTexts
Describe the structure of a phospholipid. Identify the polar (hydrophilic) and nonpolar (hydrophobic) regions of a phospholipid. Explain how the phospholipid molecules form the bilayer of the cell membrane.
