a fatty acids is most closely associated with what?
Since this is not my area of expertise, I searched Google under the key words "'fatty acids'" to get these possible sources:
http://en.wikipedia.org/wiki/Fatty_acid
http://www.elmhurst.edu/~chm/vchembook/551fattyacids.html
http://goodfats.pamrotella.com/
http://www.cyberlipid.org/fa/acid0001.htm
http://library.med.utah.edu/NetBiochem/FattyAcids/outline.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
