Where is Nervonic acid found?
It exists in nature as an elongation product of oleic acid (18:1 Δ9), its immediate precursor being erucic acid. Nervonic acid is particularly abundant in the white matter of animal brains and in peripheral nervous tissue where nervonyl sphingolipids are enriched in the myelin sheath of nerve fibers.
What is erucic acid used for?
The high levels of erucic acid made the oil useful in the production of lubricants. Today there remains a market for a high erucic acid rapeseed oil for use in plastics, lubricants, lacquers, and detergents.
Is erucic acid bad for health?
Erucic acid – a naturally occurring contaminant present in vegetable oil – is not a safety concern for most consumers as average exposure is less than half the safe level. But it may be a long-term health risk for children up to 10 years of age who consume high amounts of foods containing this substance.
