Explanation:
Detailed explanation-1: -Lipids are composed of carbon, hydrogen and oxygen atoms, and in some cases contain phosphorus, nitrogen, sulfur and other elements.
Detailed explanation-2: -Phospholipids. Phospholipids are a class of lipids that have two fatty acyl molecules esterified at the sn-1 and sn-2 positions of glycerol and a head group linked by a phosphate residue at the sn-3 position.
Detailed explanation-3: -Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.
