using the lipid-soluble spin trap 2-methyl-nitrosopropane ( mnp ) , we have detected both the lipid and hydrogen-atom spin adducts in liposomes composed of a fully saturated phospholipid ( dimyristoylphosphatidylcholine , dmpc ) with various mol fractions of unsaturated phospholipid ( 1-palmitoyl-2-arachidonoylphosphatidylcholine , papc ) or fatty acid ( arachidonic acid , aa ) .
