WebAug 31, 2024 · Phospholipids are prevalent in the cells of bacteria and eukaryotes. They are molecules made of a phosphate head and a lipid tail. The head is considered water-loving or hydrophilic, whereas the tail is hydrophobic, or repellent to water. Phospholipids are therefore called amphiphilic. WebApr 30, 2024 · A phospholipid is a lipid that contains a phosphate group and is a major component of cell membranes. A phospholipid consists of a hydrophilic (water-loving) head and hydrophobic (water-fearing) tail (see figure below). The phospholipid is essentially a triglyceride in which a fatty acid has been replaced by a phosphate group of some sort. WebPhospholipids are the most common lipids present in cell membranes. The majority of phospholipids are composed of a glycerol backbone connected to a phosphate group and two fatty acids. Because the phosphate head group is polar, it can make hydrogen bonds with water and is thus hydrophilic. jobs to help rebuild houston
