 In the blood, albumin is the main transport protein for fatty acids,
 containing at least six binding sites for FAs. 
+The unbound free fatty acids in the plasma are excreted in urine.
 Fatty acids can readily be transported across plasma membranes because of their
 lipophilicity, but concentration is small in spaces devoid of FA binding
