Explanation:

Phospholipids are made up of the glycerol molecule,the head and the tail.The head contains the phosphate group and it’s hydrophilic which means easy interaction with water and the tail contains fatty acids which repels water.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
