Omega-7 fatty acid
From Infogalactic: the planetary knowledge core
Lua error in package.lua at line 80: module 'strict' not found. Omega-7 fatty acids are a class of unsaturated fatty acids in which the site of unsaturation is seven carbon atoms from the end of the carbon chain. The two most common omega-7 fatty acids in nature are palmitoleic acid and vaccenic acid.[1]
Rich sources include macadamia nut oil and sea buckthorn oil.[citation needed] A lesser but useful source is avocado fruit (25,000ppm).[2]
The monounsaturated omega-7 fatty acids have the general chemical structure CH3-(CH2)5-CH=CH-(CH2)n-CO2H.
