title: [In vitro study of delta-6- and delta-5-desaturation of linoleic and dihomo-gamma-linolenic acids in WKY rats on a high-sodium diet].
abstract: Delta 6- and delta 5-desaturation activities of linoleic [1(4)C] and dihomo-gamma-linolenic [2(14)C] acids are increased, in vitro, in liver microsomes of normotensive rats WKY, which receive an hypernatriuric diet (NaCl 3%). These results lead to a best known of delta 6- and delta 5-desaturases, which are involved in fundamental steps of linoleic acid metabolites biosynthesis, implicated in blood pressure regulation.
