Etude Des Phospholipides De Pseudomonas Solanacearum Présence D'acides Gras α-hydroxylés Monoéthylénïques
Published 1981 · Chemistry
Abstract The phospholipids isolated from Pseudomonas solanacearum consist mainly of cardiolipids and phosphatidyl-ethanolamine. This last fraction can be separated into two fractions, one of which contains only non-hydroxylated fatty acids and the other one a mixture of hydroxylated and non-hydroxylated fatty acids. Non-hydroxylated fatty acids consist of hexadecanoic acid, Δ 9,10 -hexadecenoic acid, Δ 11,12 -octadecenoic acid and a C 17 cyclopropane fatty acid, the structure of which has been established as 9,10-methylene-hexadecanoic acid. The hydroxy acid fraction is a mixture of 2-hydroxy-hexadec-9-enoic and 2-hydroxy-octadec-11-enoic acids, accompanied by low amounts of isomers having the double bond one carbon further from the carboxyl end.
