Palmitoleic acid, a composition of fatty acid, is implicated in the prevention of death from cerebrovascular disorders in SHRSP rats.In Vitro: Palmitoleic acid is a kind of fatty acid in human milk. Among SHRSP given various fatty acids, a diet containing 1% Palmitoleic acid significantly improves the survival rate, with concomitant reduction in the incidence of stroke in spite of their excess NaCl intake through 1% NaCl water for drinking[2].
