Detailed explanation-1: -The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.

Detailed explanation-2: -11.3Lipids Lipids, also commonly known as fats, are composed primarily of carbon and hydrogen. Due to this, lipids are predominantly hydrophobic molecules that do not dissolve with water. Lipid molecules may also contain limited amounts of oxygen, nitrogen, sulfur, and phosphorous.

Detailed explanation-3: -Lipids are hydrophobic (“water-fearing”), or insoluble in water, because they are nonpolar molecules. This is because they are hydrocarbons that include only nonpolar carbon-carbon or carbon-hydrogen bonds. Lipids perform many different functions in a cell.
