Description |
Phosphatidylcholine (once given the trivial name lecithin ) is usually the most
abundant phospholipid in animal and plants, often amounting to almost 50% of the
total, and as such it is the key building block of membrane bilayers. In
particular, it makes up a very high proportion of the outer leaflet of the
plasma membrane. Phosphatidylcholine is also the principal phospholipid
circulating in plasma, where it is an integral component of the lipoproteins,
especially the HDL (High Density Lipoprotein). It is a neutral or zwitterionic
phospholipid over a pH range from strongly acid to strongly alkaline
(Ref.1).
There are two mechanisms for the biosynthesis of
phosphatidylcholine. Choline itself is not synthesized by animal cells, but is
obtained from dietary sources or by [...] |
