What is Lauric acid?

Dodecanoic acid is a straight-chain, twelve-carbon medium-chain saturated fatty acid with strong bactericidal properties; the main fatty acid in coconut oil and palm kernel oil. It has a role as an antibacterial agent, a plant metabolite and an algal metabolite. It is a straight-chain saturated fatty acid and a medium-chain fatty acid. It is a conjugate acid of a dodecanoate. It derives from a hydride of a dodecane.
