Gene Information

General description

Oleic acid (OA) is a fatty acid. OA is widely used as a surfactant for the stabilization of magnetic nanoparticles synthesized by the traditional coprecipitation method. Monodisperse magnetite nanoparticles (diameter = 7 and 19nm) coated with oleic acid (OA) have been prepared.

Application

Oleic acid may be used in the preparation of 10-hydroxyoctadecanoic acid and methyl ester of 10-hydroxyoctadecanoic acid.

Mycobacterium avium subsp. paratuberculosis (MAP) is an obligate intracellular pathogen that infects many ruminant species. The acquisition of foreign genes via horizontal gene transfer has been postulated to contribute to its pathogenesis, as these genetic elements are absent from its
