Unsaturated Fatty Acids and Pain

open access: yesBiological and Pharmaceutical Bulletin, 2011
Fatty acids, which are the essential nutrients for humans, are an important source of energy and an essential component of cell membranes. They also function as signal transduction molecules in a range of biological phenomena. Recently, an increasing number of physiologic and pharmacologic reports on fatty acids have improved our understanding of the ...
