Where it comes from
Biosynthetic pathway: Fatty acid derivatives — enzymes cut fat chains into fragments you can smell.
Why it sits where it does
A six-membered lactone ring with a five-carbon side chain. Heavy and polar, so it sits at the very end of the band and lasts a very long time.
Where else you meet it
Condensed milk, butter, coconut, peach, and heat-treated animal fat.
