Detailed explanation-1: -Key Points. 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.
Detailed explanation-2: -1: A phospholipid consists of a head and a tail. The “head” of the molecule contains the phosphate group and is hydrophilic, meaning that it will dissolve in water. The “tail” of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water.
Detailed explanation-3: -Answer and Explanation: Phospholipids are able to form barriers and act as a membrane as the phosphate head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating).
Detailed explanation-4: -Hydrophilic Head Function The function of the hydrophilic heads in the amphipathic phospholipids is to interact with water. In a phospholipid bilayer, the heads of the phospholipids point outward and are able to interact with the aqueous environment outside and inside the cell.
