Number of fatty acids present in a molecule of phospholipid is
Open in App
Solution
The correct option is B Two
The phospholipids are composed of a molecule of glycerol or other alcohol having a phosphate group joined to one of its outer -OH groups, two fatty acid molecules linked to other -OH groups and a nitrogen containing base bound to the phosphate group. Thus it has a strongly non-polar and hydrophobic tail consisting of fatty acid chains and a polar and hydrophilic head comprising a negatively charged phosphate group and a positively charged base. Because of this dual solubility the phospholipids are called amphiphatic lipids.Thus, the correct answer is option A.
