What are the chemical components of cell membranes?
Proteins and lipids.
The main components of cell membranes are lipids and proteins. Cell membranes are composed primarily of phospholipids arranged in a bilayer, as well as integral and peripheral membrane proteins. This is known as the fluid mosaic model. Components of cell membrane 1. Phospholipids 2. Glycoproteins 3. Carbohydrates 4. Cholesterol
No, carbohydrates are NOT a major components of cell membranes, which are mainly comprised of lipid (fat molecules). Proteins sit in and on the membrane and SOME of the proteins are glycosylated, which means that they have sugar or carbohydrate attached to them. So there are carbohydrates in cell membranes, but they are not a major component.
Many highly reactive molecules can affect the cell membranes negatively by modifying the chemical structure of the double layer of lipids that constitute most of these membranes. The most reactive of these molecules are strong oxidants, which can damage other molecules and the cell structures of which they are a part. Phosphorous is an essential nutrient, as it assists and strengthens energy metabolism, DNA structure, and cell membranes. Zinc is both an antioxidant enzyme co-factor…
