So what are liposomes, exactly? |Representation of a
phospholipid molecule showing phosphate head (orange), the
glycerol sholders (blue) and the fatty acid tails (silver)| The
bilayer structure of liposomes is nearly identical to the
bilayer construction of the cell membranes that surround each of
the cells in the human body. This occurs because of the unique
composition of phospholipids. The phosphate (source of "phospho"
in phospholipid) head of phospholipids is hydrophilic — it loves
water — whereas the fatty-acid tails (lipids) are hydrophobic —
they hate water. |Liposome containing vitamin C. Currently
liposome-encapsulation is the best oral way to deliver vitamin C
known to man.| |This diagram of a liposome cutaway shows how the
tails of phospholipids turn inward to form a bilayer membrane,
and in so doing encapsulate a therapeutic agent.| Quite possibly
both processes occur. In any case, the therapeutic value and
greatly increased delivery of liposome-encapsulated drugs and
nutrients has been scientifi
