Dear Babu,
You will be probably disappointed but there are no
special lipids in mammals. Except some exotic
molecules, one finds in this group all lipids that
were described in all animals and even in plants.
There is a common catalogue for all living species and
a great effort is necessary to identify lipid
molecules specific to some rare species. If you are
doubtfull, have a look to www.cyberlipid.org
