- Structure of the plasma membrane (article) | Khan Academy
Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions
- The cell membrane review (article) | Khan Academy
Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates
- Plasma membrane and cytoplasm (article) | Khan Academy
Plasma membrane (cell membrane) is made of two phospholipid layers, or a type of lipid with hydrophilic heads on the outside and hydrophobic tails inside It is also known as a phospholipid bilayer
- Fluid mosaic model: cell membranes article - Khan Academy
What’s it made up of? The cell membrane is primarily made up of three things: 1 Phospholipids 2 Cholesterol 3 Proteins
- Biological macromolecules review (article) | Khan Academy
For example, a carbohydrate is a macromolecule that is classified as a polymer because it is made up of repeating monosaccharides, but a fat (lipid) is a macromolecule that cannot be further classified because if you look under the 'monomers' column, it is built up by more than one monomer
- Homeostasis and cellular transport (article) | Khan Academy
The plasma membrane (or cell membrane) is primarily made up of molecules called phospholipids Phospholipids have one end (a “head”) that is hydrophilic (water-attracting) and one end (a “tail”) that is hydrophobic (water-avoiding)
- Nucleic acids (article) | Macromolecules | Khan Academy
How DNA carries this information, and how it is put into action by cells and organisms, is complex, fascinating, and fairly mind-blowing, and we’ll explore it in more detail in the section on molecular biology Here, we’ll just take a quick look at nucleic acids from the macromolecule perspective
- Introduction to macromolecules (article) | Khan Academy
Some carbohydrates store fuel for future energy needs, and some lipids are key structural components of cell membranes Nucleic acids store and transfer hereditary information, much of which provides instructions for making proteins
