Editing Fatty acid (section)

===Even- vs odd-chained fatty acids===
Most fatty acids are even-chained, e.g. stearic (C18) and oleic (C18), meaning they are composed of an even number of carbon atoms. Some fatty acids have odd numbers of carbon atoms; they are referred to as odd-chained fatty acids (OCFA). The most common OCFA are the saturated C15 and C17 derivatives, [[pentadecanoic acid]] and [[heptadecanoic acid]] respectively, which are found in dairy products.<ref>{{cite journal|doi=10.3945/an.115.011387|pmid=27422507|pmc=4942867|title=Pentadecanoic and Heptadecanoic Acids: Multifaceted Odd-Chain Fatty Acids|year=2016|last1=Pfeuffer|first1=Maria|last2=Jaudszus|first2=Anke|journal=Advances in Nutrition|volume=7|issue=4|pages=730–734}}</ref><ref>{{cite journal|doi=10.1096/fasebj.8.15.8001737|title=The Animal Fatty Acid Synthase: One Gene, One Polypeptide, Seven Enzymes|year=1994|last1=Smith|first1=S.|journal=The FASEB Journal|volume=8|issue=15|pages=1248–1259|doi-access=free |pmid=8001737|s2cid=22853095}}</ref> On a molecular level, OCFAs are biosynthesized and metabolized slightly differently from the even-chained relatives.
