Phospholipids are amphipathic in nature? Justify.
Answers
All of the lipid molecules in cell membranes are amphipathic (or amphiphilic)—that is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“water-fearing”) or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.
NCERT based Answer for Class 11 Biology Students
Phospholipids:
These are triglycerides where one fatty acid is replaced by phosphorylated organic compound.
Amphipathic in nature carrying both hydrophilic polar and hydrophobic non-polar groups.
Hydrocarbon chains of two fatty acids function as hydrophobic non polar tails.
Phosphorylated organic compound behaves as hydrophilic polar head.
In aqueous medium phospholipids molecules arrange themselves to form a bilayer.
Hydrophilic polar heads of molecules lie in contact with water while non polar tails are towards centre of bilayer.
Lipid bilayer is the basic component of all cell membranes.
Lecithin is a phospholipid that occurs in cell membrane.
